New York and Los Angeles-based GreeneStreet Films (GSF) has purchased the screenplay and the rights to John Searles' novel Strange But True.

Ross Katz brought the project to GSF and will produce with the company, which will finance and produce. Katz and GSF previously collaborated on In The Bedroom and are working on the romance Adverbs based on Lemony Snicket novelist Daniel Handler's book.

Searles wrote the screenplay to Strange But True, from his novel about a young woman who turns up on the doorstep of her long dead boyfriend's family and announces she is pregnant by him.

'John wrote a powerful, mesmerising story that we think will make a terrific and compelling film,' GSF founder and president John Penotti said. 'We are thrilled about our third collaboration with Ross and look forward to a wonderful shoot.'

'I devoured John's book over one long evening,' Katz said. 'That he turned it into an equally original and compelling screenplay, is remarkable. GreeneStreet deemed this a movie to make right away, and our collaboration together has been creative and exciting.'

CAA brokered the screenplay deal with GSF's Vicki Cherkas, head of business affairs, business development and new ventures. CAA in conjunction with Joanna Pulcini Literary Management brokered the rights deal with Cherkas.

Searles is the deputy editor of Cosmopolitan magazine, and recently signed a two-book contract with HarperCollins.
