Anne Hathaway is making the transition from actress to producer. The star has closed a deal to produce and topline Puzzler, a thriller set up at Paramount. The project is described as a female-driven, paranoid thriller in the vein of Three Days of the Condor. Karl Gajdusek, who wrote the recent Nicolas Cage-Nicole Kidman thriller Trespass, will pen the script. The project would mark Hathaway's first producing effort. Joining her as producers are Adam Schulman, Sarah Perlman and Stefan Sonnenfeld, who has a first-look deal with Paramount. Hathaway's recent credits include One Day, Love and Other Drugs and Alice in Wonderland. She co-hosted the Oscars in February and will star as Catwoman in next summer's The Dark Knight Rises.
