4. 'The Pink Panther' (1964)
The first Pink Panther spawned a franchise of comedy-mystery movies featuring Peter Sellers as bumbling French police detective, Inspector Jacques Clouseau. His interactions with his manservant, Cato, are priceless. Clouseau ordered Cato to attack him when he least expected it to keep him alert. This usually resulted in a ruined romantic encounter or the total destruction of Clouseau's apartment.
