Jackie Gleason's scenes were filmed first because he was ill and he wanted to be finished with the movie as soon as possible.
To the chagrin of the stunt crew, the Turbo Trans Ams didn't have quite the performance they were hoping for. So to get a respectable amount of speed out of them, they installed nitrous oxide tanks.
After critics panned the film and his work as Director, Hal Needham took out a full page ad in 'Variety' depicting himself sitting on a wheelbarrow full of cash.
At least at the time the movie was made, this picture contained one of the biggest car chases in film history. Publicity stated that it involved sixty stunt-men and stunt-women, one hundred cars and eighteen wheeler trucks. When the sequence was concluded, US $250,000 worth of vehicles had been smashed.
The roller coaster destroyed in the movie is the old "Greyhound" coaster that was located at the Lakewood Fairgrounds in Atlanta, Georgia. It was due to be torn down and rebuilt after being deemed in unsafe condition so its destruction was written into this movie. It was also shown in the background during the first Agarra-me se Puderes (1977) movie.
