John Powers

Critic-at-large John Powers reflects on what he thinks is the single greatest movie ever made about the city of Los Angeles — Killer of Sheep, an independent film made in the late '70s by Charles Burnett. It's on the Library of Congress' National Film Registry; it will be showing in selected theaters in the next few months, and it comes out on DVD this September.

Children of Men, the breathtaking Alfonso Cuaron film based on P.D. James' dystopian-futurist novel, has just come out on DVD. Critic-at-large John Powers takes a look at one of 2006's most talked-about movies.

This year marks the 200th anniversary of the abolition of the slave trade in Britain. The new movie Amazing Grace is about the British abolitionist movement, focusing on the man who led the fight in Parliament. It's a story that can lead to introspection.
