You may have already heard about this, but I came across it for the first time and thought I would pass it along. According to Peter Jackson, The Beatles were extremely interested in making a Lord of the Rings movie which they would star in themselves. Of course, J.R.R. Tolkien said no way.
John Lennon was the one pushing for the film project to get made back in the 60's. He wanted to play Gollum in the film. Paul McCartney would have played Frodo, Ringo Starr would take on Sam and George Harrison would have taken the role of Gandalf. Lennon even approached Stanley Kubrick about directing the film!
Jackson said in a previous interview with People,
It was something John was driving, and J.R.R. Tolkien still had the film rights at that stage, but he didn't like the idea of the Beatles doing it. So he killed it.
I honestly can't even imagine what a LOTR movie would have been like if done by The Beatles and Kubrick. It just seems like an insane combination of talent and material!
According to blastr, McCartney was glad the movie fell through because, "it would've put the spotlight on Lennon, who wanted the showiest role, and potentially irked the other Beatles: 'The strength of the other films which we made is that we're all equal.'"
It would have definitely been an interesting movie to see!
