The scene depicted on this film's main American movie poster, that of Steve Martin riding on a two-seater bicycle with a dog, is not actually seen in the movie.
An Australian movie poster press-ad featured a joke questionnaire. It said: "YOU KNOW YOU'RE LONELY WHEN: A. Your inflatable doll has a headache. B. You have long, intimate conversations with your pet fern. C. Your answering machine puts you on hold. D. You drive the wrong way down a one-way street so someone will wave at you. E. You eat garlic and nobody notices."
Ed Beheler: As a Jimmy Carter look-alike. Credited as this, it is not actually clear though whether this cameo is meant to be the former American president (he vocally sounds like him) or an impersonator.
