Let's Go Crazy is a 1951 comedy film marking an early appearance of Spike Milligan and Peter Sellers playing multiple roles.

Detective Inspector Jacques Clouseau is borrowed from the Surete on special assignment for Scotland Yard in hopes that a fresh outlook will help the government recover the loot from the Great Train Robbery, which is being used to underwrite a new crime wave. What they don't count on, however, is having more than one Clouseau on the job.
