The fourth and final collaboration between Director Carl Reiner and Steve Martin might also be their funniest, second only to "The Jerk". Martin play attorney Roger Cobb, who aspires to be made a partner in his law firm but can't give up his passions for playing jazz guitar, and therefore isn't taken seriously by his boss. He's sent to deal with dying eccentric (i.e. rich and weird) client Edwina (lily Tomlin), who's figured out some way to put her soul into her stable hand's daughter's (Victoria Tennant) body when she dies, unfortunately, the guru drops the bowl containing her soul out the window and it hits Cobb on the head as he's walking out the door. All this is of course just an excuse to set Martin loose with some of the best physical comedy of his career, as Edwina controls half his body while he retains the other half. The movie itself may not be very clever (physical comedy and clever rarely go hand-in-hand), but compared to "The Jerk", it's downwright understated. The interchanges between Tomlin and Martin are pretty entertaining, and transition between their inner dialogue (in Cobb's head) and Martin's outer manifestation of Edwina's personality is tightly choreographed. This is probably one of Steve Martin's best comedic performances in what is a very enjoyable movie.
