Dwayne Johnson has landed a starring role in New Line's earthquake disaster flick, San Andreas.  The picture will be directed by Brad Peyton, who previously worked with Johnson in Journey 2: The Mysterious Island.  Originally scripted by Andre Fabrizio and Jeremy Passmore, with Chad and Carey Hayes currently penning the rewrite, San Andreas follows the devastation after a California earthquake and sees a man (Johnson) embarking on a dangerous trip to rescue his estranged daughter.  The character, as described by Heat Vision, is a "rugged rescue helicopter pilot".  Since Johnson is officially on board, New Line has set April as a start date for production with a planned release in 2015.  Johnson is currently filming James Wan's Fast & Furious 7, after having just wrapped on Brett Ratner's Hercules: The Thracian Wars.
