The late James Baldwin was one of the most influential African-American writers to emerge during the civil rights era. During the late 1950s and 1960s, he traveled through the South and addressed racial issues head on. Though Baldwin died in 1987 before that book could be written, the new Oscar-nominated documentary, I Am Not Your Negro, draws on his notes for the book, as well as from other of Baldwin's writings.

In August 1966, a student and former Marine ascended to the top of the tower that housed the University of Texas' main library and began shooting at people below. He killed 14 people on the campus and wounded 31 more. Hours earlier, Charles Whitman had killed his wife and mother in their homes. He was eventually shot to death by police. A 15th victim died in 2001, from injuries sustained in the attack. Now the new documentary Tower re-creates that 96-minute-long massacre in an original way, using archival film and new interviews with an animated portrayal of the events.

In a striking documentary, Sarah Polley turns the camera on her own family. The director and actor, known for films such as Away from Her and The Sweet Hereafter, was teased growing up about not looking like her actor father. At 27, she discovered that it wasn't a joke.
