"I talk to [Cameron] all the time," Worthington said. "I talked to him last week. I think at the moment he's still doing the ['Avatar'] bible, the book, and I think the book will then inspire where he wants to take it," the "Clash of the Titans" star explained. "He's got great ideas; what he told me about, where he wants to set it, things he wants to explore. We'll probably talk next year, and then he can fill us in on where, personally, he wants to take it, where emotionally he wants to take it."
Regarding the sequel's underwater setting, Worthington said only some of the action will take place in the water.
"[Cameron] is going to explore that [underwater] world," he said. "It won't fully take place underwater but he's definitely going to explore same as the mountains, he can explore more, outer space [as well] it's up to him," Worthington added. "He created the world."
And finally, we asked Worthington about the future of Jake Sully, specifically whether audiences will ever see his human form onscreen again. Worthington said he had "no idea."
