Tony Gilroy is in talks to take over the fourth Bourne film. Not that he's ever been far away from controlling them - he's scripted all of them since Doug Liman's initial Bourne Identity.

Provisionally titled The Bourne Legacy, the fourth outing for Jason Bourne has already been written by Gilroy, who was hired back in June to scribble something down on paper. With Paul Greengrass taking himself out of the director's chair last year, Universal need a man to sit at the helm. And the Michael Clayton man isn't a bad choice at all.

Whether we need another adventure for the amnesiac spy now that he's got all his memories back is another question entirely. Matt Damon has already said that he won't return without Greengrass, so the studio will be on the hunt for either a new central character or a new Damon replacement.

The Bourne Legacy was originally scheduled for 2012, but that timetable's up in the air at present. Expect something to get locked down in the next couple of months.
