John Travolta, Chuck Norris to join 'Expendables 2'?

John Travolta and Chuck Norris are said to be joining the cast of The Expendables 2.

David Varod, the head of the Bulgaria-based NU Boyana studios - where the movie will shoot - claimed that the two actors will be starring in the follow-up to last year's ensemble action film.

When asked what stars would be heading to Bulgaria, Varod told Novinite: "Sylvester Stallone, Jason Statham, John Travolta, Arnold Schwarzenegger, Chuck Norris, Jean-Claude Van Damme, Dolph Lundgren, Mickey Rourke... who else? Of course, Bruce Willis.

"The director is Simon West, who is also a name. He is already here and has started working on the film. I believe the sequel will be better than the first movie."

However, Jet Li, who appeared in the original film, is notably missing from Varod's list.

Varod also revealed that the film will begin shooting in September.

"The shooting is going to take place in the second week of September," Varod said. "The movie is on, definitely."

Van Damme was cast as one of the film's main villains in May, despite turning down an appearance in the original.

The Expendables 2 opens in cinemas on August 17, 2012.
