As they were preparing to shoot Still the Beaver, the creators were trying to locate Rusty Stevens to reprise "Larry Mondello." They hired a detective to locate him. The detective found the right house and knocked on the door. Rusty's wife answered and the detective asked her if it was the residence of the former child star. She replied that he had the wrong house. Later, she told Rusty and he responded that the detective had the right house; apparently, he didn't tell his wife about his past life as Larry Mondello! Unfortunately for other cast members whom they wanted to reprise their roles, they were not so lucky.
