Probably the some violence category, if I remember the movie well enough. They are competing against each other to get to the prize after all. It's more like cartoon violence though, like Wacky Races except more tame.
I spent like 3 hours making that list. I had a lot of movies to look through and I spent for too much time trying to figure out what to include and which category they go under. Not sure I'm up for spending more time on this. I don't even know what letterboxd is.
