Three movies with big name casts opening at theaters this weekend

Friday the 13th will be a lucky day for moviegoers with three new films hitting theaters.

They include the a film that represents almost every action movie of the last 30 years, one based on a popular independent comic about a guy dealing with his girlfriend's exes, and the latest from Julia Roberts based on a memoir about a woman's trip around the world.

Here's what's new in theaters.

The Expendables could be called the dream action movie of the 1980s, with Sylvester Stallone, Dolph Lundgren, Mickey Rourke, Arnold Schwarzenegger and Bruce Willis all appearing in some capacity. It's about a team of mercenaries who are hired to take down a South American dictator but soon find out not everything is as it appears.
