Stacy Keach learned to drive a 16-gear semi truck in just two days for the role of Quid. He drove the truck about 1,600 miles during the production.
The story that Quid tells Hitch while camping is actually the true story of that particular filming location. The camp scene was shot at a ruined old telegraph station that used to serve an Australian town that was destroyed by a plague of rabbits many years earlier.
The American distributors wanted Richard Franklin to cut the 360 degree pan shot of Quid talking on the phone in the roadhouse. They felt the shot was too long and added nothing to the story. Franklin, however, refused to cut the shot.
Jamie Lee Curtis said she felt a certain amount of hostility and prejudice while on set, being one of the two "token Americans". One of the crew members even approached her and asked, "What is it like putting Australians out of work?"
In the original script the name of Quid's dog was supposed to be Bosco. However when Stacy Keach told Richard Franklin that Bosco was actually a chocolate drink in America the name of the dog was changed to Boswell.
