Yahoo! Movies recently posted the trailer for writer/director Wayne Kramer's Crossing Over. Some films are for purely popcorn purposes but every so often one gets you to start thinking and Crossing Over is that film. You can click below to enjoy the trailer.

Immigrants from around the world enter Los Angeles every day, with hopeful visions of a better life, but little notion of what that life may cost. Their desperate scenarios test the humanity of immigration enforcement officers. In Crossing Over, writer-director Wayne Kramer explores the allure of the American dream, and the reality that immigrants find - and create -- in 21st century L.A.

Crossing Over moves into theaters December 3, 2008 from The Weinstein Company.
