Larry Pizer: When Maude and Dancy are first out shopping for horses, right after he tells her that he wants her to know that he can be trusted, there is a shot of an older man standing next to a horse and it's handler and gesturing. That's Larry Pizer, the D.P.
Arthur Fellows: the producer is seen in two shots as the horses head though a tunnel on the way to the track for the Derby. He's the balding man with glasses holding a program on the right of both the long shot and medium shots in that scene.
