Wrestlers are great enough actors to fool millions of fans to think their sport is real. I wouldn't call The Rock a "great" actor - but he's awesome at being a bad-ass. I haven't had the chance to see Man with the Iron Fists yet so I can't say anything about Bautisa's performance. If all he needs to do is be intimidating and bring the pain, I don't see how it'll be a stretch for him. I mean, how many other misses has Marvel had casting-wise? I trust them.
