In a land far, far away, it could have been Jason Bourne or the Prince of Persia running around Pandora.
James Cameron, acclaimed director of 'Avatar' approached both Matt Damon and Jake Gyllenhaal about playing the role of Jake Sully in the film, which now stands as the biggest movie in History with over $2.5 billion dollars taken worldwide from Box Office sales alone. Not to mention the fact it's catapulted Sam Worthington to massive stardom, and put him in the running to play the legendary James Bond.
Lucky for Sam Worthington though, both actors declined, perhaps because they considered it too risky, or not serious enough. Cameron however was relieved because Worthington was his first choice, saying he only offered the role to the big-name stars to subdue the concerns of studio chiefs who wanted a bigger name to offset some of the enormous expenses incurred from the project.
"I don’t think they ever had a problem with the CG, “Cameron said. “Honestly, did I go out and try to woo them? No. I had my heart set on Sam. Maybe they sensed my lack of 100% commitment from me. Maybe it was the subject matter. This was a big 'Star Wars'-type movie. They’re both serious actors.”
