Curse of the Pink Panther(1983)

Overview:

Inspector Clouseau disappears, and the Surete wants the world's second best detective to look for him. However, Clouseau's enemy, Dreyfus, rigs the Surete's computer to select, instead, the world's WORST detective, NYPD Sgt. Clifton Sleigh. Sleigh obtusely bungles his way past assassins and corrupt officials as though he were Clouseau's American cousin.
