Sam Worthington says the staggering worldwide success of “Avatar,” over $2.5 billion at the box office, makes him wonder if multiple sequels will be made, as the actor expressed his willingness to work with James Cameron yet again. The 33-year-old actor said the innovative director could bring another groundbreaking technique to the sequels.

“I’m starting to think we’re going to do ‘Avatar 3, 4, 5’, but that’s the thing, we’re only going to do it if Cameron can find someone to challenge him because he’s not the type of guy that just dives in lightly.”
