"Help!" was such a late decision for the film title, that when Capitol Records released the first single, "Ticket To Ride" / "Yes It Is", the A-Side was credited as being from the film, "Eight Arms To Hold You".
George Harrison said that during the filming of the sequence in which the Beatles threw a hose out the window and the army guards all fall down, they were in hysterics laughing and the scene took almost a day to film.
George Harrison was introduced to the sitar during the filming of the club scene, which features an Indian band playing an instrumental sitar version the song "Hard Day's Night".
George Harrison, whom Richard Lester said was the best actor of the Beatles, has more material in this film than in the previous Beatle film.
Richard Lester said that at the store Aspreys in Bond Street, John Lennon spent £8,000 during a two minute break.
Judy Cornwell says in her memoirs she was asked to appear in this project but had to pass because she was very pregnant.
Ken Thorne's musical score is largely made up of elaborate orchestral re-arrangements of "A Hard Day's Night", "You Can't Do That", and "From Me to You" by The Beatles.
A miniaturized Paul is wearing flesh-colored bathing trunks during his brief (no pun intended) "nude scene" in "The Exciting Adventures of Paul On The Floor". The discarded chewing gum wrapper which he uses to wrap around himself as a towel is clearly intended to resemble a Wrigley's Spearmint Gum wrapper, although no brand name is shown.
A scene cut from the film, was to have been within the attempts to kill Ringo, (within the five attempts), it involved Ringo making a phone call in a phone box, and a blotched sacrifice attempt made within the phone box.
According to Paul McCartney, the script was designed around their requests that the story involves them going to places like the Austrian Alps and the Bahamas because they had never been there before.
According to still photos included in the "making of" documentary on the new Special Edition DVD, one of the features in Ringo's apartment space that was not used in the movie was a little dining room table and chairs in the vending machine wall that would pop out in the same manner as Paul's organ.
According to The Beatles, they were experimenting in marijuana at the time this movie was filmed. That explains why they flub alot of their lines or their lines don't make much sense.
Beatles producer George Martin joined the Beatles in the Alps for a skiing vacation, while they filmed there, but hardly got to enjoy it; he broke his ankle the very first day. Also, while Martin had provided the instrumental soundtrack for A Hard Day's Night, he and Richard Lester hadn't gotten along, and Lester chose Ken Thorne for "Help!"'s instrumental score; in Martin's own words, "I was included out."
Beatles' reading material: The book John takes from the shelf and kisses before settling down to read, is his own "A Spaniard in the Works." Meanwhile, Paul has a selection of Superman comic books atop his organ. (In the novelization of the movie, the book John selects is "Les Liaisons Dangereuses", aka "Dangerous Liaisons".)
Before the ski shot in the Austrian Alps, The Beatles told Richard Lester that they had never skied before. Lester handed them skies and told them, "What better time to learn, find a hill, and practice!" Lester said in a later interview, "We set cameras to follow them around, then gave those tapes to the Editor to create parts of the 'Ticket to Ride' scene."

By Paul and Ringo's own admission, they were so stoned on pot the day they shot the scene where Dr. Foot and Algerman tried to blow them up in the Austrian Alps that when George screamed his line "It's an fiendish thingy! Run Ringo!" Both Ringo and Paul ran over the next hill.
Due to time constraints, the film was edited while it was being shot. So by day Richard Lester would shoot the film, and by night he would edit any scenes that had been completed.
During the closing credits, the Beatles and their co-stars take turns appearing as reflections in a giant ruby. During this sequence, George can be heard in voice-over, proclaiming "'I Need You' written by George Harrison!" and repeating this same information twice. As the movie ends, John's image is the last that appears in the ruby.
