The 1970s: a time for Reggie Jackson, the first go-round of John Travolta, and adopting a chimpanzee to settle a scientific dispute. The new film Project Nim by director James Marsh, the documentarian behind the acclaimed Man On Wire, debuted at the Sundance Film Festival in Utah this week. Marsh tells the tale of a chimp that was taken from its mother and raised in a human family just like a human baby; the experimenters were attempting to show that language is not unique to our species.
