AvatarEveryone is just going to have to wait a little longer for the "Avatar" sequels.

While "Avatar 2" was scheduled for release Christmas 2018, director James Cameron told the Toronto Star that the movie won't be ready by then.

"Well, 2018 is not happening. We haven't announced a firm release date," he said.

The delay comes as no surprise, considering Cameron has plans to film the four sequels back to back.

"What people have to understand is that this is a cadence of releases. So we're not making 'Avatar 2.' We're making 'Avatar' 2, 3, 4 and 5. It's an epic undertaking. It's not unlike building the Three Gorges dam."

Cameron has also been busy helping design the new "Avatar"-themed park at Walt Disney World, as well as producing the documentary "Atlantis Rising." He's also tinkering with new technology for the "Avatar" movies.

"I know where I'm going to be for the next eight years of my life. It's not an unreasonable time frame if you think about it," he added. "It took us four-and-a-half years to make one movie and now we're making four. We're full tilt boogie right now. This is my day job and pretty soon we'll be 24-7."
