I'm sure someone else has noticed this, but I haven't seen any posts.
Aren't there several lines/scenes from "Help" that gave us a clue as to the Beatles' future?
"Filthy Eastern ways" - Wasn't Yoko accused of that?
"I don't want to knock anybody's religion, but..." - Maybe they WERE bigger than Jesus.
"Are you sure it's not habit forming?" - Wasn't Paul the one who had concerns about taking acid?
"Only me and Paul know we're here." - Once again, George and Ringo being left out of the loop.
"We have all sorts of little problems like this, sir. Some of them matrimonial!" - Said to John, just a few years before his divorce.
"It's a different religion from ours... I think." - Ringo, thinking silently during a Maharishi lecture.
"You're a rat underneath, aren't you?" - Paul, to Ringo, in the film. Also Paul, to Ringo, during the legal feud.
Then there's the scene at the airport (before the Bahama scenes) where the Beatles are in disguise. Just a few years later, those wouldn't be disguises, would they?
And of course the scene that always gets a standing ovation at Beatlesfest, when Foot points the gun at John and it misfires. If only...
