Empire Online reports that the rumors about Peter Jackson's interest in having Guillermo del Toro direct the big screen adaptation of the hit video game Halo are absolutely true.

del Toro – who’s currently in Madrid, where he’s in post-production on his new Spanish-language fantasy film, Pan's Labyrinth – is torn between committing to the Universal movie, or reuniting with his favourite comic character for Hellboy 2.

How do we know this? Well, we spoke to our old chum Guillermo yesterday and he confirmed that when he finishes work on Pan’s Labyrinth – “the best thing I’ve ever done, that’s not saying much but I’m sure of it! It’s really beautiful, man!” – he has a quandary.

Hellboy 2 is still awaiting the big greenlight, before filming can take place (partially in the UK, fact fans). “We’re budgeting,” said del Toro. “I’m very much looking forward to it. I wanna do it. It’s still on the front burner, but it’s all about budget.”

“Well, Halo is very much an interesting project because it’s so full of monsters,” he said. “It’s a big temptation. I’m in talks with them [Universal and Bungie Films] and Peter, but it’s not true that it’s on and Hellboy’s off. Hellboy’s on. If everything goes as planned, Hellboy will go.”

An avid gamer, del Toro has been a big fan of Halo for some time. “Most of the time games don’t have an universe or creatures that interest me enough. And this one does. Master Chief [Halo’s mysterious hero] is such an iconic character and it’s very much a sort of a good version of [Hellboy villain] Kroenen.”

One factor in Halo’s favour is that, from Doom to Resident Evil to Super Mario Bros., there hasn’t yet been a good game-to-film transfer. “No, there hasn’t,” agrees Guillermo. “I really love the technical and visual challenges of the movie. It’s a very intense game and I thought it was very cinematic. The game is structured in many ways like a movie. It could kick some ass.”
