I watched two Bud Spencer and Terence Hill movies, and will be watching two other ones shortly too (all were on TV recently)
this one can best be avoided, even though it does have a 7.2 ranking on IMDB. It's a bit too much outdated with stereotypical stuff like Italians (or whatever white people they were) with black curly wigs playing aboriginals, and a Japanese war veteran that still believes after 30+ years that the war hasn't ended
This one was very entertaining though, it has some funny spoofs on the spy / cop movies such as James Bond.
Fun fact: Bud Spencer (the big guy) was an Olympic swimmer and the first Italian to swim the 100-meter freestyle in less than a minute.
