George Segal originally was cast in the lead role but walked off the set shortly after filming began. Rumor had it that this was because Dame Julie Andrews' role had been built up. Allegedly, after the movie had been released, Segal was asked if he had seen it, and he replied by giving "the finger". This marks the first time that George was replaced by Dudley Moore. This happened again for the title role of Arthur (1981). Conversely, in The Mirror Has Two Faces (1996), Moore was replaced by Segal.

When George is driving past the limo (as Jenny arrives at her wedding), he is driving on the wrong side of the road, having crossed a double-yellow line, and crashes head-first into a police car. The officer gives George a ticket for an expired license, no registration, and reckless driving, yet George is allowed to drive away. The officer even yells at George to "Go on, move it!"

When the credits of the cast begins to scroll up and out of the iris of the telescope's view into George and Samantha's penthouse, the members of the cast are listed but not the characters they played.

The TV print substitutes tamer versions for some of movie's racier moments. In particular, scenes featuring porn star Annette Haven as Dudley Moore's exhibitionist neighbor have been removed, replaced with scenes involving another actress. On scene features Moore's character using a telescope to watch a naked Haven making love. (In the TV version, a substitute actress kisses a man while wearing a robe.) A later nude orgy is replaced by a similar scene, but with everyone wearing bathing suits. In addition, the comedic lovemaking scene between Derek and Moore is played in the dark in the TV version.
