This movie was one of two sequels that Jackie Gleason starred in and were released during 1983 which were both plagued by not featuring original cast members. Smokey and the Bandit Part 3 (1983) did not star Burt Reynolds and Sally Field whilst The Sting II (1983) did not star Robert Redford and Paul Newman.
Director Jeremy Kagan once said of this movie: "'The Sting II' is inspired by and is an expansion of the first 'Sting' rather than a continuation. The principal characters of Fargo Gondorff and Jake Hooper are based on two real-life con-men and are totally different from the original . . . 'The Sting II' has more comedy and the nature of the con is more intriguing. Now the con men themselves are being conned."
Both times that Hooker rides the Coney Island roller coaster, his cap stays neatly in place, on his head, for the entire ride. In reality, that type of coaster can reach speeds of 60-70mph. His cap should've blown off during the first drop.
The Coney Island Roller Coaster train is made of fiberglass, not wood, as a 1940s coaster train would be. Fiberglass was introduced commercially in 1936, but it was used mostly as insulation. It wasn't used for applications like roller coasters until well into the 1950's.
