3D has been the big focus of this year’s San Diego Comic Con, so it’s no surprise that when you get a bunch of movie industry visionaries together, watching movies while wearing funny glasses is a front and center topic. EW attended the Visionaries Panel at Comic Con tonight where Peter Jackson and James Cameron took center stage, and talked 3D.

In particular, Cameron confirmed that a 3D version of Titanic is coming. In fact it’s already underway, though the conversion process will take 18 months. Cameron said, “We've seen a couple of minutes already, and it looks great.”

On the other hand, 3D doesn’t seem to be in the cards for Lord of the Rings. Now that New Line Cinema is all but defunct, Warner Bros. is in charge of the Lord of the Rings universe and Peter Jackson says they aren’t enthusiastic about converting them. What’s the problem? They just don’t think there are enough 3D screens out there to justify the expense. They’re probably right.

Right now pushing 3D is Hollywood’s way of pushing us towards a future where it’s the norm, it’s not really about making big profit from it now. 3D is the long view. Some are buying into it, other like Warner Bros. apparently aren’t. Give the choice though, I think I’d rather watch Frodo leap out of the screen than be forced to watch Leonardo DiCaprio drown into the row in front of me.
