Here's what he had to say about the decision to convert, with one of the reasons being he wants to shoot the sequel on film instead of digital.
"The big question was to shoot native 3D or not. I tested a lot of digital cameras, and quite frankly, because I'm going for a sort of much grittier, grounded look in Clash 2, the look I want is almost Gladiator with fantastical creatures in it, I found that the characteristics of film were more what I was going for."
The director also revealed he was hesitant about converting to 3D, given the negative backlash surrounding the conversion of Clash of the Titans. He was convinced by Warner Bros. to convert, though, after seeing the advances made in the technology.
"I didn't want to convert, but Warner Bros. showed me how far conversions have come. You've got Chris Nolan doing Inception, converting the DVD, you've got Harry Potter being converted, Star Wars being converted, so the conversion process has improved dramatically in the past two years."
"I think what you have to remember is the first film was neither shot nor edited with 3D in mind. It was shot as a 2D movie and edited as a 2D film, and they decided to convert it with six or seven weeks to go until release, which is insane; the technology was not there. That's why we're conceiving it from the start, from the ground up, in 3D, editing in 3D for 3D."
Wrath of the Titans was released March 30th, 2012 and stars Sam Worthington, Liam Neeson, Ralph Fiennes, Edgar Ramirez, Toby Kebbell, Rosamund Pike, Bill Nighy, Danny Huston. The film is directed by Jonathan Liebesman.
