Is Sam worthy?

Just when did 32 year old Australian actor Sam Worthington become Hollywood's flavour of the month? You watch Chris Pine in Star Trek, and you get it, you feel comfortable that he was the right man for the role. Pine has the on screen charisma and all the required abilities to etch out a long CV of top billing performances over the coming years. He's earnt the right to star in Tony Scott's next blockbuster. And if further roles among the Hollywood elite come his way which I'm positive they will, you feel like he has deserved it. But just what has this Aussie guy done? I'm baffled as to how he went from the killer croc movie Rogue in 2007 to starring in Terminator Salvation, Avatar and Clash of the Titans in such a short space of time, cast in all of the above before anyone had seen a single frame of his acting in those movies. I only ask because his performance in Terminator Salvation is so excruciatingly painful that I'm now worried he is going to end up as the new Colin Farrell, an actor who was pushed into roles he was never suited for. The above (and one below, after the jump) from Clash of the Titans only gave me two other reactions... 1... This movie is going to have a lot of 300 style screaming and intensity. 2... that is one big motherf'n shield.
