From The Art and Popular Culture Encyclopedia
Inspector Jacques Clouseau (later chief inspector) is a fictional detective in Blake Edwards's Pink Panther series. In most of the films, he was played by Peter Sellers, with one film in which he was played by Alan Arkin and one in which he was played by an uncredited Roger Moore. In the most recent Pink Panther film and its planned 2009 sequel, he is played by Steve Martin. Sellers is widely regarded as the definitive Inspector Clouseau of pop culture by fans and critics alike.
He is also the inspiration of the main character in a series of short animated cartoons inspired by the titles of the feature films. Though the character in the animated The Inspector was never given a name, he is clearly based on Clouseau. However, more recent animated depictions of Inspector Clouseau since the 1970s on were redesigned to resemble Sellers, and later Martin, more closely.
