number one action star in hollywood right now is still Bale. Butler's only defining role so far was 300, but that movie was awesome because of the collection of actors...not "just" him. If he get's a recurring role like Batman, than maybe. Heck, I forgot about Downey....he's probably as big or real close to Bale. Owen is still my favorite of all of them, I think he's the best actor among them with Bale being a real close second.
