Making the press rounds for the release of his latest picture, magician heist thriller Now You See Me, director Louis Leterrier has opened up about his past Hollywood blockbusters The Incredible Hulk and Clash of the Titans - including what he feels went wrong with them.

Though Leterrier was quick to dispel rumors that he didn't get along with The Incredible Hulk star Edward Norton (who is said to have offered substantial revisions to the screenplay), but he did reveal that the largest problem he faced was beginning to direct a film without a script! "[Marvel/producers] were like, 'Oh, welcome, welcome. Great news, Louis. We just got a release date. It's a year from now.' I'm like, 'Fantastic, we have to go. Where's the script?' They said, 'Actually, that's the problem, we don't have a script.' ...I've started movies without screenplays both on Clash and on Hulk and that is tremendously stressful, because you have a tendency to overcompensate with effects," Leterrier explained.

Leterrier also admitted that Joss Whedon was not alone in picturing Mark Ruffalo as the Hulk: "I actually wanted to cast Mark Ruffalo as Hulk and Marvel was like "No, you should get Edward Norton because he's more famous."

When pressed about whether he believed that Clash of the Titans' 3D - which did well at the box office but was slammed by critics - was too "rushed," the French director was quickly prompted to be even more blunt about what he faced with in helming the project:

"Yeah, exactly. [Clash of the Titans] was famously rushed and famously horrible. It was absolutely horrible, the 3D. Nothing was working, it was just a gimmick to steal money from the audience. I'm a good boy and I rolled with the punches and everything, but it's not my movie. "Clash of the Titans" is not my movie. And ultimately that's why I didn't do the sequel."

Thankfully, however, Leterrier is now sleeping a little easier with his latest movie: "[Now You See Me is] the least stressful of all of the movies that I've done. For me, the other movies I did were like, "OK, will it blow up or won't' ...This movie truly represents who I am."
