Twenty-five years ago today, John Lennon was approached by an autograph seeker whilst heading into his apartment at the Dakota. That fan, Mark David Chapman, fired a few quick shots. By the time he made it to the hospital, Lennon had died. There are a few maudlin memorials going on in New York today, but you'd be better off staying home and watching one of the many films Lennon appeared in, with the rest of the Beatles and without them. I'd start with Richard Lester's WWII satire, How I Won the War, in which Lennon co-stars as a soldier serving under the most inept commander in the whole of the British army. I'd tell you to move on from there to Magical Mystery Tour, but you probably won't be able to find it. In that case, you can't go wrong with A Hard Day's Night; it's Lennon's first screen appearance, and Lester's masterpiece.
