The fact is in Hollywood wrestling is frowned upon. The Rock had to completely cut off any association and put in the work for nearly a decade before he got serious looks to be a leading man in movies that weren't the Tooth Fairy.
For every Hogan, there was a lesser known Eddie Guerrero who got you to sink into every word he spoke until he passed away who never did a single movie. Some guys can only play one or two roles (in Hogan's case it was either American hero or cocky, bigger than wrestling Hollywood character). Others are real good actors, though. You'll never see these guys winning awards for being the best actors because they're not that good, but for what they NEED to do and for having to play their role 24/7, 365 days even when they're not on TV, they do a good job of what they need to accomplish.
