Charlaine Harris, the author of the Sookie Stackhouse novels makes a cameo in the Season 2 finale at Merlotte's. Also in the same episode, Bill Compton has a reservation at a French restaurant, and where he's written Mr, the r is superscripted, just like it was in the olden days; a reflection of his age.
To shoot the title sequence, the production crew took a 4 day trip to Louisiana, Chicago (where the church was filmed), and Seattle (for the bar scenes and writhing bodies). They would jump out of their cars as soon as they saw something they liked, or got permission to shoot people's homes, like the man in the rocking chair. He later had a few beers with them. Executive producer Mark Bayshore is the man dancing with the girl, her arm around him, and his sons are the boys with berry juice over their faces.
Michael Raymond-James hired a dialect coach to pull off a Cajun accent. The two worked closely on the script, inserting French into Rene's dialogue for effect. Some people found it hard to understand this, because his accent was that authentic. The dialect coach did the same work with Michael Jeter on The Green Mile (1999).
The Dallas hotel Sookie and Bill Compton check into in Season 2 is the hotel Carmilla, a reference to the vampire novel of the same name from 1872. The scenes at Carmilla were shot in 2 days, 18 hours for the first and 24 hours the following week. The guests brushed shoulders with Anna Paquin as well as the employees.
The exteriors for the mansion home of Russell Edgington, the Vampire King of Mississippi, and his husband, Talbot, were filmed on location at Longwood, a mansion in Natchez, Mississippi. Longwood is unusual in several respects: it is an octagonal structure, an architectural style that was otherwise unknown at the time in the region; the tower has a large, onion-shaped dome on its top; and because the Civil War interrupted its construction, it has never been completed - the family that commissioned it was never able to live in the main part of the house and instead furnished the basement. Longwood is a registered National Historic Landmark
Joe Manganiello revealed in an interview that there were plans for an emotional storyline with Robert Patrick (Alcide's father) and another with him teaching Luna's daughter what it meant to be a werewolf, but the change of showrunners in the middle of season six ditched all those ideas.
Russell Edgington favors Waterford crystal. His mansion is filled with pieces, and the urn containing Talbot's remains his also by Waterford. According to production designer Suzuki Ingerslev, the pieces were lent to the production by the owners of the famous Irish crystal manufacturers because they are fans of the show.
Each episode title is a song that always plays out over the end credits. One of the songs from Season 2, Nothing But The Blood Of Jesus had to have a line changed. It went from "white as snow" to "black as snow" to remove any connection of race and sin, and the suggestion that white is pure while black is not.
The bird lady sculpture that Sam Merlotte stole from Maryann was made in 3 days. 2 other copies were made and kept on standby. Cindy Jackson didn't mind because she was used to tight deadlines after designing toys for Happy Meals. She did it in her kitchen after her studio was demolished by a wayward driver. The sculpture was a bird lady because it best reflected Maryann's nature, which is why Michelle Forbes performed many scenes with her arms up in the air; she's supposed to be communing with her god.
While shooting some of Season 2, Ashley Jones was concurrently appearing in The Bold and the Beautiful (1987). She often went without sleep between shifts. She also has a no-nudity clause written into her contract, even when the casting call insisted on it. So whenever Daphne's character involves anything like seduction, its done in silhouette instead.
The Fellowship of the Sun church is the Sky Rose chapel at Rose Hills memorial park in Whittier, California. Its 15 miles East of downtown LA. Its the largest cemetery in the US with over 600 employees. It was one of the first to offer all services of memorialization.
After Alan Ball left the showrunner position after season 5, Mark Hudis took over. But after a few episodes of season 6 had been shot, Hudis was replaced with Brian Buckner, who ran the show until the end.
During Season 1, we see the coffins of the three members of Malcolm's nest. One of the coffins in the nest (specifically the green marble one) has "Gott ist tot" written repeatedly around it's side. "Gott ist tot" is German for "God is dead".
Alexander Skarsgard's character has a relation with his brother's, Bill and Gustaf, characters in Vikings and Hemlock Grove. Bill plays a upir, a vampire who can walk in the sun, in Hemlock Grove. Gustaf plays a viking in Vikings.
Zack Snyder is reportedly a huge fan of this series and "noticed" Joe Manganiello as a possible Superman even before signing in for Man of Steel (2013). Manganiello was about to make a screen test with a Superman suit when HBO stepped in and prohibited him from any auditions due to contractual obligations with this series.
Bill Compton was born on April 9, 1840, and died (made into a vampire) on November 25, 1868, according to the novels. Although he has the appearance of a 28 year old man, he is 168 years old in the pilot episode.
Stephen Moyer had already appeared as a vampire in the excellent UK TV series Ultraviolet. He was the best friend, Jack Beresford, of the main character Michael Colefield who was played by Jack Davenport.
Mehcad Brooks, Britt Morgan, Jim Parrack and Joe Manganiello would all portray DC Comics characters in later productions. Parrack portrayed Frost in Suicide Squad (2016), Manganiello is set to star as Deathstroke in "The Batman" (both set in the DC Extended Universe). Brooks and Morgan guest-star in Supergirl (2015) as James Olsen and Livewire, respectively. Joe Manganiello was also considered for the role of Clark Kent/Superman in Man of Steel (2013).
In the novels, Bill isn't as much of a leader as he is in the show. He takes orders from Eric and pines after Sookie. Bill and Sookie date briefly, but she doesn't reciprocate his affections after he cheats on her with his maker, Lorena.
Eric's storyline for the last season was resolved two episodes before the finale because Alexander Skarsgård had to begin shooting The Legend of Tarzan (2016). In fact, according to showrunner Brian Buckner, the only reason why Eric is at all in the last two episodes, with minimum screentime, it's because Skarsgård demanded it so to the producers of the movie, since it was the ending of the show.
Every season has a main antagonist for the protagonists to face. Season 1: Rene Lenier. Season 2: Maryann Forrester Season 3: Russell Edgington Season 4: Marnie Stonebrook Season 5: Salome Agrippa and Lilith Season 6: Sarah Newlin and, in the finale, Warlow. Season 7: Sarah Newlin is the cause of the problem for this season, but Hep-V is the primary problem.
