Part one taught me almost nothing new (though I saw some awesome footage I'd never seen before) about George and his time with The Beatles, but the second half of the movie taught me so much, not only about George's life, but how he lived his life.
The first film I can remember ever loving (age 3). It is an absolute masterpiece, and is still just as funny today as it was in 1927. Keaton was a genius and a madman (he did all of his own stunts, most of which you couldn't get away with today). Simply stunning.
