The actress with the most Charmed Fan Mail is actually not one of the main stars of the show. Actress Finola Hughes who plays Prue, Piper, Phoebe and Paige's mother receives the most fan mail from Charmed series viewers.
Telekinesis is the most common power in the Halliwell line. Carriers include Melinda Warren, Prue, Penny, Chris, Wyatt, Paige and the granddaughter from 'Forever Charmed'. Piper's freezing power has only recurred in her mother (apart from Melinda Warren) and Phoebe is the only witch that is known of (apart from Melinda Warren) to receive the premonitions power. Although once in season three, Patty Halliwell spoke of having a premonition the day that she found out she was pregnant with Phoebe, also the same day the sisters traveled back in time to change their future. Patty's premonition came from the fetal Phoebe.
During the first few seasons when Constance M. Burge was Executive Producer the series had more focus on the girl's sisterly ties and discovering their witchly heritage. That changed when the show's reigns were handed over to Producer Brad Kern and the focus shifted more to vampy outfits and consistent relationship issues.
Holly Marie Combs was shot mainly in close-up and wore baggy clothes for most of season six to hide her real life pregnancy until it was written into the storyline to explain Chris' conception and birth.
Brian Krause who plays Leo Wyatt, Julian McMahon who played Cole Turner, and Kerr Smith, who appeared in season seven as Agent Kyle Brody, had all auditioned for the role of Inspector Andy Trudeau, who was a character played by actor Ted King in season one.
The show's popularity inspired toy company SOTA Toys to create 6.5" action figures of the characters: Piper, Phoebe, Paige and Belthazor which come with interlocking attic walls and a miniature Book of Shadows. Originally an alternate toy of the Prue character was to be made, but actress Shannen Doherty declined to the offer to have her likeness made into a Charmed doll.
The house used for the exterior shots of the "Manor" is located at 1329 Carroll Ave in the Echo Park Section of Los Angeles. (The same house was used for the exterior of the tall woman's house in Deuce Bigalow: Male Gigolo (1999).)
During hiatus between seasons two and three, producers discussed possible storylines for season three. Executive Producer Brad Kern wanted to bring in a season long love interest for the Phoebe character who started out bad but becomes good. Fellow Executive Producer and show creator Constance M. Burge was against the idea as the character Piper already had a convoluted season long relationship storyline and she wanted to focus back to the sisterly dynamic of the show. After realizing that she wasn't going to win the debate, Burge left the series and full production reigns fell to Kern.
Throughout the series, the Sisters continually lose and gain powers, swap and share powers with demons and experience short periods of newfound powers. The season 1 episode "Love Hurts" is unique, as it is the only episode in the series where any of the sisters exchange powers amongst each other. (In the season 7 episode "Ordinary Witches", Piper and Phoebe attempted to swap powers. But an interruption from an unforeseen attack caused their powers to land in two unsuspecting civilians.)
In the episode 'All Halliwell's Eve' in season 3, it is revealed that the name of Phoebe's true love would begin with the letter 'C'. Later in season 8 when it was announced that the show was in it's final season they brought in the cupid character 'Coop' for Phoebe, meaning that 'Cole' was never Phoebe's true love, only her first love. The writers made the name begin with a 'C' on purpose.
Although in the series Piper is the oldest sister, Phoebe the middle sister and Paige the youngest, Alyssa Milano is actually the oldest of the three actresses, being born in 1972. Holly Marie Combs and Rose McGowan are both born in 1973.
Whenever an actor stands at the front door of the real Halliwell Manor, it is obvious that there is no central hallway in that house since a wall is right behind the actor. The inside of the real house was used for the pilot show, however every other show was filmed on a much larger set on a sound-stage.
Prue and Phoebe's past lives are the only witches in the line not to receive Warren powers. Phoebe had pyrokinesis (the ability to create fire) and Prue had cryokinesis (the ability to generate ice). Similarly, Paige's past life could control the elements although we only saw her control wind and fire.
The actresses that played Prue Halliwell (Shannen Doherty) and Penny 'Grams' Halliwell (Jennifer Rhodes) are both in the movie Heathers (1988). In further connection to the movie - the character Jason Dean (Eric Dane)is introduced. Jason Dean (also known as "J.D." for short) is the name of Christian Slater's character in the movie "Heathers." The church Paige's friend Glen is about to marry in is also the same one where Heather Chandler's funeral was held in "Heathers."
After Prue quit Buckland's Auction House, she was employed as a photographer at "415" magazine whose title is also the area code for San Francisco telephone numbers. The magazine was mentioned at other times throughout the remainder of the series including when Phoebe, as the writer of the "Ask Phoebe" column, posed for the magazine.
Before either Shannen Doherty or her replacement Rose McGowan were on "Charmed", they both played valley girls (Numbers 2 and 3) in a short cameo in the movie Nowhere (1997). (Their dialog together is listed on the Memorable Quotes page for that movie.)
Piper's career change, resembles that of fictional character Louisa Trotter; the main character from the BBC series "Duchess of Duke Street." Both she and Piper initially aspired to become great chefs but wound up the proprietor of a well known establishment.
In a screening of the reality medium program 'Lisa Williams, Life Among the Dead' - Lisa was asked to visit an address to investigate a possible haunting. The house she visited was on the same street in Los Angeles as the Charmed Manor. The house can actually be seen in the background as Lisa is filmed exiting her vehicle.
Among the most powerful villains that the Sisters face throughout the series, are the opponents Barbas, The Triad, Cole Turner (in all of his forms), The Source, The Hollow, The Shadow, The Titans, Zankou, Billie and Christy.
Rose McGowan revealed in an interview (October 2014) that she thought she signed up for two seasons because she was told that by the producers, and was happy doing those episodes, but when the ratings kept going up and the show was renewed for more seasons, she found out she had signed for five seasons in total, which was actually the amount of time she worked on the show.
During the course of the show the sisters drove the following vehicles: Prue drove a Mazda Miata and later a BMW SUV, Piper drove a Jeep Cherokee, Phoebe drove a Mini Cooper and Paige drove a Volkswagen Beetle.
During the eighth season in January 2006, Spelling Television and producer Brad Kern claimed that Charmed had become the longest running TV series with all-female leads, surpassing "Laverne & Shirley" (1976). However this is not true as "The Facts of Life" (1979) actually ran for nine seasons, which is a year longer than Charmed.
At the end of the pilot episode, the newspaper Prue is holding shows the same headline that inspired Robin William's character Daniel to use name Mrs Doubtfire in the titular movie. "Police Doubt Fire Was Accidental". However, it is not the same newspaper. Prue is holding the Gazette whereas Daniel was reading the Chronicle.
Kit the cat, turned out to be the Charmed Ones' familiar; spirit guide. Since being adopted by the Halliwells, Kit would disappear from time to time and not be seen for days. A possible explanation was given in the season 5 episode "Cat House" when Paige mentions that a cat like Kit used to hang outside of her loft. Most likely, Kit was keeping an eye on Paige due to her charmed heritage even though she was not yet apart of the power of three.
Each time Cole struggled with his evil side, he would become physically sick. (Such can be seen in each of the three seasons where Cole was featured; struggling against Belthazor, against the Source and against the collective demonic powers he gained in the Astral plain.)
Wyatt's powers were never fully listed. But some of the powers that he's shown using on the show are, Orbing, conjuring (without casting spells) summoning the dead (at will) Pyrokenesis, telekinesis, power swapping, dematerialization, prescience, shrinking, putting up force fields and healing.
Throughout the series, a common motif surrounding the character Phoebe was that should she was susceptible to giving up on love. When she summoned her future self, she encountered an unmarried, bitter woman with strong resentments; yet somehow she was willing to sacrifice her life for Cole which may have changed the future in which she never married him. Despite this, it seemed that Cole's ultimate betrayal left such a lasting impact on Phoebe that while watching her from a distance he had to intervene and indirectly convince her never to give up on love. This eventually led to her meeting Coop who became the love of her life. In summoning her future self, Phoebe changed her future of dying to save her old love and made way for her to meet a new one.
Among the many stages of the magical hierarchy, it's possible that The Tribunal is the highest level. Composed of a high council of Elders and Demons, they serve to protect all forms of magic. Other magical entities such as The Angel of Death and The Angels of Destiny, operate on their own (without answering to either side) and serve to keep balance in the cosmos. The Avatars existed entirely outside of this. Their powers maintained the cosmos in a way beyond good and evil but cost people their free will.
Throughout the series, Leo's orbs always elevate no matter where he's traveling. (Even when traveling down to the underworld or back down to earth from the Heavens.) He's the only Whitelighter who does this.
Cole has on numerous occasions, saved the Charmed ones with either his demonic powers or his knowledge of the other side. From the time when he first assisted Phoebe in tackling Dantalian the Dark Priestess, Cole has often been the "Deus Ex Machina" that saved the power of three.
Every season ends with a door closing. It is usually the manor's door shutting, but the sixth season ends with the hospital door shutting after Chris was born. In the last season the door is shut by Piper and Leo's granddaughter using telekinesis, the same way Prue used to do.
The Charmed Ones coven never learned that Cole had joined the Avatars years before they became aware of them. At the time, Cole realized that the Avatars needed a great power like his; possibility for his invulnerability. The way the Avatars power collective works, is by pooling great sources of power; with their commons goal as a possible "anchoring point." Like this, the collective operated almost like single body with each Avatar as limbs and organs. Their only weakness, was the ancient potion which can kill them. In the case of Cole Turner's addition to the collective, The Avatars may have been able to share in his invulnerability; eliminating the threat of the potion and making them truly unstoppable.
The trivia items below may give away important plot points.
In season 1 when Phoebe's premonition power grows and she is able to see the past for the first time she sighs and says "Somehow I thought I was gonna get to fly". Later in season 3, she gets the power of levitation which was later cut out due to dangerous and expensive stunts and replaced with the power of empathy.
The concept of Cupid is first introduced in Season 2. In season 8 Phoebe is assigned her own Cupid as the Elders fear she has lost hope about love. In the series finale, her nephews from the future inform her that the Elders assigned Coop, her personal Cupid, with hopes that she would fall in love with him and in the final sequence their wedding is briefly shown.
Until the appearance of the character Chris Perry in the fifth season finale episode "Oh My Goddess", the only male witches shown on the series have all been children. Richard was the only other male witch until he gave up his powers for Paige.
Piper struggled to find a name for her first child that would start with P in order to retain the family heritage. But they came to the realization that they didn't have to follow that tradition since the child was a boy. Since the child is a boy, they wanted to pay homage to the father's side and Leo's surname becomes the baby's first name - Wyatt.
