Former 80's action rivals Sylvester Stallone and Arnold Schwarzenegger are to finally team up on the big screen.

The Governor of California is the latest action star to sign up for Stallone's epic movie The Expendables.

The man on a mission film, which will be directed by Stallone, tells the story of a group of mercenary misfits who attempt to overthrow an evil South American dictator.

The cast reads like a who's who of action cinema. Jet Li, Jason Statham and Danny Trejo will also star alongside Arnie and Sly.

The film has also managed to land some heavyweight acting talents including Forest Whitaker and Mickey Rourke. Could this be the best action cast ever?

Sir Ben Kingsley reportedly dropped out and is being replaced by Eric Roberts - which admittedly is not quite the same thing!

It's believed Arnie's appearance will only be a cameo in the film.
