Sylvester Stallone, Arnold Schwarzenegger co-star in 'Escape Plan'

Sylvester Stallone and Arnold Schwarzenegger are teaming up for another action packed movie.

The best friends star in the upcoming film "Escape Plan," which tells the story of a structural-security chief "who finds himself set up and incarcerated in the world's most secret and secure prison [and] has to use his skills to escape with help from the inside."

According to DNAIndia, the actors were very competitive with each other on the set and were even spotted getting into a fake brawl while filming. Director Mikael Hfstrom was reportedly so impressed that he decided to included the sequence in the film.
