Yeah, I don't see the problem with it really. It seems a bit much to complain on the basis that they're keeping people out of work to be honest. I don't see why one person should be defined by one job - if wrestlers or rappers want to act and think they can do a good job then let them. Just in the same way a screen-writer or editor might want to direct or a director might want to act or an actor might want to direct a film or...etc etc. You get the point.
