Bradley Cooper and Robert De Niro can’t keep away from each other – or from Philly

Bradley Cooper. Robert De Niro. Philadelphia. It's a love triangle that just won't quit. Next month, the two stars -- teamed in Limitless, which was mostly shot here -- are heading back to Phillywood to make The Silver Linings Playbook. Adapted from the sharp, funny Matthew Quick novel about a high school teacher who suffers a  breakdown, goes off to a mental clinic, returns home to live with Mom, has trouble patching things up with his wife and tumbles for the sister-in-law of a good friend, The Silver Linings Playbook is being helmed by David O. Russell, Oscar nominated earlier this year for The Fighter. Cooper and De Niro head the roster, along with X-Men: First Class and Winter’s Bone star Jennifer Lawrence. (Cooper is the perplexed protagonist, Pat Peoples; De Niro his dad, and Lawrence the girl Pat pursues, who has her own problems.) Chris Tucker has also been cast, according to Variety, playing an ward-mate buddy of Cooper's.

Cooper, of course, hails from Rydal, just outside the city, and attended Germantown Academy.
