Tonight’s prime-time doubleheader on TCM features individual movies by two Seventies movie stars who, a few years later, would team up for the classic All the President’s Men: Robert Redford and Dustin Hoffman. And each of their respective movies tonight is an epic, rugged period piece, starting with Redford’s 1972 film, directed by Sidney Pollack, about a Rocky Mountain trapper in the 1830s. Redford is captivating here, playing against his matinee-idol looks, growing a grisly beard, and even confronting a grizzly bear.  It’s a poignant, poetic Western, quite unusual, and the landscape and weather are major characters. To Redford, they also were a major inspiration – it’s why he established his Sundance Film Festival in that part of the country in Utah, and why he moved there.
