Big Mouth, The (1967, USA) C-107m. *½ D: Jerry Lewis. Starring Jerry Lewis, Harold Stone, Susan Bay, Buddy Lester, Del Moore, George Takei. Sloppily directed comedy made by Lewis at the decline of his skill. He plays the character he had portrayed for almost two decades, an idiot, who learns of a diamond loot from a dying criminal. He checks into the hotel where the diamonds are supposed to be, taking up another identity (one awfully similar to his 'Buddy Love'). Hardly funny, needlessly long, only his fans might find some value here.
