Is there a thread about this movie? I saw a preview recently and it looks awful. Mike Tyson and Steven Seagal? https://www.youtube.com/watch?v=AMiaXULFpLw (There's about 5 previews in there, each one as confusing and terrible as the last.)
I have friends with kids in gymnastics. That's a thing they all say and I'm sure pre-dates the movie. In fact, that was probably the entirety of the pitch.
