A Shot in the Dark (1964)
The second in the 'Pink Panther' series is by far the best. Peter Sellers is probably one the greatest physical comedians of all time (save Charlie Chaplin), and he's at his best here. His Inspector Clouseau has been mimicked countless times, but none packs the same delivery as Sellers. His completely clueless attitude coupled with a sense that every pratfall is someone else's fault is just too funny. Herbert Lom is good as a supportive role, a chief inspector that has to put up with the bumbling Clouseau. But it's really a Sellers highlight reel. Who needs anything else?
