Jake Gyllenhaal, Mark Ruffalo and Robert Downey Jr will all take lead roles in the movie, which is due to roll before cameras in August.

Jake Gyllenhaal, Mark Ruffalo and Robert Downey Jr will take the lead roles in a forthcoming flick that examines the identity of legendary serial killer Zodiac, who terrorised New York during the 1960s and '70s.

Directed by David Fincher ('Se7en', 'Fight Club'), 'Zodiac' will be based on Robert Graysmith's book of the same name as well as its sequel 'Zodiac Unmasked: The Identity of America's Most Elusive Serial Killers Revealed'.

The killer was never caught, but Graysmith, a cartoonist at the San Francisco Chronicle at the time, believes he discovered his identity, only to be ignored by police.

Zodiac's story was loosely adapted in 1971 as the Clint Eastwood blockbuster 'Dirty Harry', although this version, obviously, will have a very different ending.

Ruffalo is slated to play the chief investigator on the case, Downey Jr a reporter and Gyllenhaal will take centre stage as the writer/cartoonist.

The books are currently being adapted by James Vanderbilt ('Basic', 'Darkness Falls'), with production slated to start in August.
