WME has acquired the well-regarded boutique lit agency Rabineau Wachter Sanford & Gillett (RWSG) Literary Agency. The agency, run by Sylvie Rabineau and Jill Holwager Gillett, has been a wellspring of tasteful material that formed the basis for the upcoming films The Girl On The Train, The Snowman, Extremely Loud And Incredibly Close, Diary Of A Wimpy Kid and such TV projects as The Leftovers, Olive Kitteridge, and the upcoming Berlin Station.

Rabineau (whose husband Steve recently joined the agency as a partner after a run at UTA) and Gillett will become co-heads of WME’s Book to Film/TV division. RWSG’s Geoffrey Sanford becomes an agent repping his list of authors. Liza Wachter will exit to pursue various philanthropic and producing projects, per WME.

“This acquisition builds upon WME’s commitment to great storytelling and our love of books. With Sylvie and Jill at the helm, we are thrilled to extend our great resources to embrace the co-agent community,” said WME’s Head of Books Jennifer Rudolph Walsh. “Sylvie and Jill are responsible for bringing some of the most iconic projects to the screen and we can’t wait to have them bring their vision, strategic thinking and expertise to WME.”

Rabineau and Gillett, in a joint statement, said, “By joining WME, we are excited to continue working with storytellers across all media and having the exceptional resources, expertise and support of such an innovative and dynamic company.”
