Roadside Attractions have unveiled the first official trailer for upcoming documentary feature Project Nim.

Directed by James Marsh (Man on Wire), Project Nim stars Bob Angelini, Bern Cohen and Reagan Leonard.

Nim is a chimpanzee who, in the 1970s became the focus of a landmark experiment which aimed to show that an ape could learn to communicate with language if raised and nurtured like a human child.

Project Nim premiered at the 2011 Sundance Film Festival, and will be shown simultaneously at the 65th Edinburgh International Film Festival and the 2011 Sheffield Doc/Fest in June.
