Sam Worthington is one of the worst actors who gets major film roles in the history of cinema. The guy expresses nearly no emotions at all....his face is practically expressionless throughout the movie. His voice drones like he is reciting the dictionary. How does he still get major film roles?!?! He has NO presence/charisma either. I actually think he is a worse actor than Keanu Reeves.
If the guy could do martial arts, perhaps I could watch him in a few movies.
Watch the movie Last Night...you can't possibly tell me this guy is an average or above average actor. How about Avatar? HAHAH! How did the critics completely ignore his terrible performance in virtually every scene?!?!?! It's one of the great mysteries...that and who really killed JFK.
