Sherlock Jr.

Sherlock, Jr. arguably exceeds The General as Buster Keaton's greatest achievement -- it is certainly more magical in its use of extraordinary special effects and unconventionally humorous situations. Movies about movies are a dime a dozen, but rather difficult to do well. Keaton's brilliant structuring of the story -- a fantastic treat for audiences when his pathetic projectionist becomes the genius detective through a literal entering of the movie screen -- has been imitated dozens of times, but I always come back to this unsurpassable rendering. Watching Keaton play the scene where he studies how to go about kissing his best girl by peeking at a movie version of the same event always reduces me to simultaneous jags of tears and laughter.
