Pink Panther, The (1964)
Sellers is great, the rest not so much
The film has a problem and that is simply not enough Sellers. When he is on the screen the movie lights up because he is very funny even though he is not yet using the trademark over the top accent. He is great in all his scenes, and makes those scenes work. No one else is particularly funny and they many times try to act a little too zany, which does not work out nearly well enough. It is clear why in the sequels they dropped every one else and kept Sellers.
