“I wanna feel good about something some time,” conflicted Border Patrol agent Charlie Smith explains as he returns a stolen infant to its dispirited mother, a Guatemalan refugee seeking a new life in the United States. Such is the conflict at the heart of this 1982 critical and box-office failure from director Tony Richardson. The Border has taken on a cult status over time, with an 80 percent favorable rating from Rotten Tomatoes. Jack Nicholson was one of the top movie stars (Easy Rider, Chinatown, One Flew Over the Cuckoo’s Nest, The Shining) when he came to El Paso, where The Border was mostly shot. Nicholson’s is an understated performance. He leaves the histrionics to others in a nuanced portrayal of a Border Patrol agent torn between his own borders — doing what’s right and doing what’s wrong amidst growing financial pressures at home. With music by Ry Cooder.
