Back in October, we reported that director Guillermo del Toro is working on the Pacific Rim 2 script with original Pacific Rim writer Travis Beacham, although that isn't quite the case anymore. During a recent interview for his upcoming FX TV series The Strain, Guillermo del Toro revealed he is now writing the script with Zak Penn (Marvel's The Avengers, The Incredible Hulk). Here's what the writer-director had to say, revealing that Travis Beacham is no longer involved due to his new TV series Hieroglyph getting picked up at Fox.

"I'm working very, very hard with Zak Penn. We've been working for a few months now in secret. We found a way to twist it around. Travis Beacham [co-writer of the first film, now working on Fox's Hieroglyph] was involved in the storyline and now I'm writing with Zak because Travis has become a TV mogul."

The director also said that, while Legendary Pictures has not given the official green light for the sequel, he's writing the script in hopes that it will move forward.

"I don't have the money, but I'm proceeding like it is happening."

Back in December, Pacific Rim star Max Martini hinted that Pacific Rim 2 may actually be a prequel. Guillermo del Toro confirmed that it is in fact a sequel that will follow the events of the first movie, with Raleigh Beckett (Charlie Hunnam) and Mako Mori (Rinko Kikuchi) set to return.

"Some people were wondering if we were going to do the prequel. I was never interested in doing that first wave of invasion. I'm going for very new, very crazy ideas on the second one, which are very different from the first one - but you will get really great spectacle."

Pacific Rim only pulled in $101.8 million domestically, but it fared much better overseas, with a worldwide total of $411 million, $111.9 million of which came from China alone.
