The dancing priest in "Happiness is A Warm Gun" (the scene in the hospital) is choreographer Daniel Ezralow.
Events in the movie are derived from actual 1960s events, such as the violent student protest at Columbia University. The actual explosion at a New York townhouse was the work of the Weather Underground and took place at 18 West 11th Street in Greenwich Village; a photograph of the actual house appears in the movie. The Beatles were also stopped by police while playing a rooftop concert in London.
The shipyard employee that gives Jude his paycheck says he thought he'd be doing something different when he was sixty-four, an allusion to the Paul McCartney's song "When I'm Sixty-Four."
When Prudence first enters the apartment through the window, Jude comments "She came in through the bathroom window," a reference to The Beatles's song "She Came in through the Bathroom Window."
After Prudence enters through the bathroom window, Jude greets her saying "Hello, hello" which can be seen as a reference to "Hello Goodbye", which was called Hello Hello by McCartney while he was writing it.
The stained glass windows in Jude's apartment feature 45 RPM records as the center of the flowers.
Cafe Huh? is a reference to Cafe Wha?, originally in Greenwich Village.
When Max and Jude first see their apartment, Sadie comments that Max seems harmless, but could have murdered someone with a silver hammer, and in another scene Max is shown holding a silver hammer, both homages to the song that lends Max his name, "Maxwell's Silver Hammer." It's made all the more obvious by Max tapping the hammer and creating the beat of that very song.
When Jude takes inspiration from the bowl of strawberries, he creates a Jackson Pollock-styled "splatter" painting. This seemingly alludes to Stuart Sutcliffe, once a bassist with The Beatles, who was a painter in the Jackson Pollock style.
The intro of the film version of "If I Fell" is borrowed from The Beatles's intro to "Good Day Sunshine."
The Cavernous club seen in the UK side of the alternating vignettes at the opening of the film is the Cavern Club in Liverpool where The Beatles played in the 60s.
Apple Records, the studio owned by The Beatles, is referenced when Jude is trying to draw a green apple, then slices it in half, thus producing the two logos of the company. The close-up shows a sliced apple almost exactly as it is on the logo.

The character of JoJo is a clear reference to Jimi Hendrix. Sadie dresses him up in the purple shirt and bandanna - one of Jimi's most famous stage costumes. JoJo also plays a Fender guitar - the same brand played by his prototype, Jimi Hendrix - however, Hendrix played a Fender Stratocaster, while JoJo plays a Fender Telecaster.
Sadie, with her fiery red hair and passionate temper, is a reference to Janis Joplin. Sadie is even seen drinking directly from a Jack Daniels bottle during her downward spiral, an action that Janis did regularly with Southern Comfort. Even Janis' throaty singing voice is used by Sadie in the movie.
While JoJo's character is a reference to Jimi Hendrix, it is also a reference to The Beatles's song "Get Back", particularly the first line "JoJo was a man who thought he was a loner/But he knew it wouldn't last."
Release prints were delivered to some theaters with the fake title "Love and Freedom".
Though the character of Sadie is a reference to Janis Joplin, it is also a reference to song "Sexy Sadie" from the White Album by The Beatles.
The painted bus and Dr. Robert (Bono) singing "I am the walrus" is a reference to psychedelic painted bus The Beatles had in their film Magical Mystery Tour (1967) (TV), as well as Ken Kesey and the Merry Pranksters who traveled around the United States in his bus. The punch at the party is of course then "electric" Kool Aid, just like Kesey used at his parties. Finally, when Dr. Robert stops at "Dr. Geary's" place, this refers to Timothy Leary who also experimented with LSD and was often at odds with Kesey.

According to Julie Taymor she used 30 songs of The Beatles as a basis for the script that covers events from 1963 to 1969, but in the film those 6 years are compressed into two years.
Julie Taymor was inspired by Rafael Fracacio's O Diário de Julia (2003), a psychedelic short film, to create the lethargic experience in the bus sequence and the "I Am The Walrus" clip, in the movie.
The quote "you're either on the bus, or off the bus" is taken from the book "The Electric Kool-Aid Acid Test," by Tom Wolfe.

During the performance of Strawberry Fields, the main characters watch TV. In the counter shot we see the same image projected on their faces. This is a reference to the promotional video that the Beatles made to accompany the song when it was released.
When discussing Dr. Robert's bus Sadie's manager says "Spread the word" which is a reference to The Beatles song "The Word" found on the album "Rubber Soul."
The name Molly from Jude's Liverpool Girlfriend alludes to Molly in the Beatles song "Ob-La-Di, Ob-La-Da".
Director Julie Taymor watched the premier of Across The Universe sitting next to Paul McCartney. She was nervous about what he would think so when the movie was over she asked if there was anything he didn't like about it and McCartney responded "What's not to like?" McCartney also sang along with "All My Loving" under his breath, a very moving moment for Taymor.

Jude's life progression is similar to John Lennon's. As John Lennon did, Jude first lived in Liverpool then soon after that moved to New York City to work as an artist like Lennon.

The "Why Don't We Do It In The Road?" scene is similar to how 'Brian Epstein' discovered The Beatles.
At college, Max generally goofs off and causes trouble. This is a reference to the song lyric, "Back in school again/Maxwell plays the fool again", from the song which gives Max his name "Maxwell's Silver Hammer."
During the Thanksgiving dinner scene, Lucy's and Max's grandmother remarks that "the cranberry sauce isn't as tangy as last year," referencing the use of the words "cranberry sauce" uttered by John in the song "Strawberry Fields Forever" which was often misheard as "I buried Paul," adding to the myth that Paul was dead.
A voice is heard yelling "Get Back!" when Sadie leaves the stage during "Oh! Darling."
Later in the film, Prudence locks herself in the closet and has to be serenaded out by the other cast members. This is a reference to a real occurrence in 1968 at the ashram of Maharishi Mahesh Yogi in India where the Beatles, Mia Farrow, Donovan, and others were studying. Mia Farrow's sister, Prudence, was reclusive and did not leave her living quarters to join the other students, inspiring John Lennon to write the song "Dear Prudence." The film also uses the song as a subtle reference to the fictional Prudence character's reluctance to 'come out of the closet' in relation to her sexual orientation.

At the end of "All You Need is Love," when Jude reunites with Lucy, a voice is heard singing "She loves you, yeah, yeah, yeah," referencing the Beatles song "She Loves You." This, however can also be heard in the original version of the song, right before the end, as well as the starting lyrics for the Beatles' song "Yesterday."
While Sadie and the Po Boys are performing, you can see a Gibson J-160E Acoustic Guitar on the stage, the same model played by John Lennon.
"Because" is sung by exactly nine actors - a reference to the way The Beatles recorded the song - the 3-part harmony vocal performance among John Lennon, Paul McCartney and George Harrison is overdubbed three times to make nine voices in all.
According to the industry trade paper Daily Variety, the filmmakers had to pay the owners of the rights to their music, publisher ATV/Sony Music and Michael Jackson, about $10,000,000 for the music rights to the 30 songs used in the film (roughly $330,000 for each song). As a condition of the songs' use, the advertising posters for the film did not mention "The Beatles" nor the songwriters' names.
During the "Mr. Kite" scene, Mr, Kite says "Just tune in, turn off, drop out, drop in, switch off, switch on, and explode", which is a reference to a quote from Professor Timothy Leary.
During Jeff Beck''s instrumental cover of "A Day In The Life", Jude is seen wearing a mask and cloth cap. This is reminiscent of Ringo's wearing the exact same clothing in during his "parading" in A Hard Day's Night (1964).
The setting of the Mr. Kite scene - a small tent in the middle of a field, into which a disproportionate number of people enter - is a reference to a scene in _Magical Mystery Tour (1967)_, which also appeared as a scene in a comic book that accompanied the album.
The prosthetic faces of the soldiers during "I Want You" are casts of the face of 'Michael Balderrama', the lead dancer in this sequence.

When the bus arrives at "Dr. Geary's," Jude asks "What is that place?" To which Sadie replies "headquarters of the League of Spiritual Deliverance." An obvious reference to LSD, not only using the letters, but also referring to the experiences that Timothy Leary claimed to result from LSD.
In the scene where Jude and Molly are at the Cavern Club, one of the guitarists on stage is playing a Gretsch Duo Jet guitar, very similar to the one that George Harrison played.
