John Travolta has been added to the cast of 'Expendables 2'.

The 'Grease' actor has reportedly joined an all-star line-up of actors, including Arnold Schwarzenegger and Jason Statham, for the sequel to the 2010 action film - which was directed by Sylvester Stallone - to be filmed in Bulgaria.

David Varod, chief executive officer of NU Boyana studios, said: "It is going to be a sequel to the 'The Expendables'. The shooting is going to take place the second week of September. The movie is on, definitely. It will be a very good thing for Bulgaria, since there are some very big stars coming."

When asked who will star in the movie, he added: "Sylvester Stallone, Jason Statham, John Travolta, Arnold Schwarzenegger, Chuck Norris, Jean-Claude Van Damme, Dolph Lundgren, Mickey Rourke. Who else? Of course, Bruce Willis."

David revealed 'Con-Air' director Simon West is helming the project - which is rumoured to have Bruce lined up to play the main bad guy, with Jean-Claude thought to be set for the secondary villain role - and he thinks it will be "better" than the first movie.

He said: "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."
