Screen Media Films plans an October release after it acquired North American rights to Suzanne Mitchell’s documentary Running Wild: The Life Of Dayton O Hyde.

Barbara Kopple served as executive producer on the story about the life of Hyde and the 12,000-acre horse sanctuary in South Dakota that is home to more than 500 rescued mustangs.

The film premiered at Slamdance earlier this year and won the audience award at the Sarasota Film Festival.

Mitchell also produced and Alejandro Perez and Robert Johnson of UK-based Telecom 2 served as executive producers alongside Kopple.

Screen Media president Suzanne Blech and manager of acquisitions and marketing Seth Needle negotiated the deal with Peter Broderick on behalf of the filmmakers.
