It looks pretty good I think, also the only guy I think I know from that movie is the guy in Coach Carter,I forgot is name, but he's the white guy with the shaved head, I know it's hard to guess who that is but, there's another thing is dad is in prison.
I've never heard of it, but from your brief description, it sounds like any other of a multitude of movies that involve people switching genders (be it in disguise or somehow for real), getting trapped inside the body of someone of the opposite gender, etc.
Yesterday I just watched a trailer of it. I have never seen the movie Just one of the Guys before but you are correct. It looks pretty much like the same thing. But then again, it's not like this sort of thing hasn't been done before by other movies.
