EXCLUSIVE: Eric Warren Singer, the co-writer and exec producer for the Oscar-nominated David O Russell-directed American Hustle, has returned to CAA. Singer left the agency almost a year ago and spent the past 10 months at UTA. He most recently turned in a rewrite of No Exit, which Joseph Kosinski will direct for Black Label and Lorenzo di Bonaventura, and he’ll next write Marita for Sony, which has Jennifer Lawrence attached as star and producer with Matt Tolmach. Singer continues with attorney Mark Gochman.
