SAN DIEGO — At the recently concluded Comic-Con, there seemed to be one number and one letter on everyone's lips: 3-D. Directors like Tim Burton and Robert Zemeckis unveiled new footage flaunting it, James Cameron and Peter Jackson held panels praising it, and Hall H was equipped to show it for the first time. Now, filmmaker Jon Favreau is eager to bring it into his hugely successful "Iron Man" series.

"I really love the 3-D," the "Iron Man 2" director told us at Comic-Con, echoing the recent sentiments of Marvel Studios honcho Kevin Feige. "I think 'Up' was probably my favorite movie I've seen this year."

As fans of the franchise know, Marvel has plans to make at least one more "Iron Man" film, as well as an "Avengers" flick in 2012 that will feature Tony Stark. If Favreau has his way, he'd like at least one of those films to be three-dimensional.

"I like all the new technologies, 3-D being one of them. James Cameron had brought me around a few months back to see what he was doing with 'Avatar'; that's what's been seen now by many of the fans," he said of the 3-D footage shown by the "Titanic" filmmaker last week. "It was exciting to go in there and see what he's doing with cutting-edge technology. He's just a great storyteller as well, and to see a great filmmaker working with the cutting-edge of this technology is amazing."

So amazing, in fact, that Favreau nearly made "Iron Man 2" three-dimensional. "I talked to Marvel after I'd seen [Cameron's footage] about doing 'Iron Man [2]' in 3-D," he said. "I was hoping to get a shot at doing it this time around, but it didn't work out that way. ... There are a few drawbacks to it at this point — there's more cost involved, and it also forces you to shoot digitally. My cinematographer [Matthew Libatique] really likes film, and 'Iron Man' had a certain look because it was film."

As of right now, Favreau isn't certain he'll direct "Iron Man 3" or "The Avengers." But Feige is on record as saying that he'd like to see Marvel films jumping off the screen soon, and Favreau is convinced that the technology will be there for whichever film he makes next.

"We haven't had any talks about [me directing 'Avengers'], although we do have talks about what the content of 'Avengers' will be," Favreau said of the film expected to feature Iron Man, Nick Fury, Thor, Captain America, Black Widow and others. "I'm going to be involved in some capacity with it, but as far as directing goes, we're still working on this one. ... I'm happy they brought me back to do 'Iron Man 2.'

"But I think that, as the digital technology gets better, 3-D is going to be a lot easier," the filmmaker continued. "Certainly for 'Iron Man,' I think it would work out well."
