Perhaps the best movie in the series. I read somewhere that Sellers once said that deep down Clouseau knows he's an idiot. In this movie, Sellers actually makes the Inspector a sympathetic character.

This is the first appearance of Kato, Clouseau's servant who attacks him at random moments "just to keep him in top form," and Chief Inspector Dreyfus who is driven mad by Clouseau's stupidity.

Watch for the scene in which Clouseau interrupts the opera recital.

It's not sophisticated, but it's very funny.
