It's official.

Battle: Los Angeles director Jonathan Liebesman has signed on to direct Warner Bros. upcoming sequel Clash of the Titans 2, according to Heat Vision Blog.

We reported back in June that Jonathan Liebesman was one of the directors being considered to replace original Clash of the Titans director Louis Leterrier. The site reports that negotiations had been ongoing throughout the summer and that they hope to overcome the negative reactions to the first film, despite its $491 million worldwide gross. The film will be shot in 3D, as opposed to the rushed post-production conversion job on Clash of the Titans.

Dan Mazeau (The Flash) and David Johnson (Red Riding Hood) are writing the script for the sequel, based on a treatment written by Greg Berlanti (Green Lantern), Dan Mazeau and David Johnson.

Sam Worthington and Gemma Arterton are both expected to reprise their lead roles for Clash of the Titans 2. Our original report from June indicated that Warner Bros. was eyeing a January 2011 start date for Clash of the Titans 2, but that date may change.
