Production Weekly has updated its Twitter feed today with news that three high-profile films have settled on start dates. First up, the site is reporting that Clash of the Titans 2 has been given a, "tentative start date of February 2011." During a press event last week, star Sam Worthingtonrevealed that the film would be shot in 3D, as opposed to the first Clash of the Titans's 3D post-production conversion.

The site also reported that Peter Sollett's adaptation of Brian K. Vaughan's Marvel comic series Runaways had set a shooting schedule from January 2011 through June 2011.
