Happy to be back: Arnie at The Expendables 2 premiere

Arnold Schwarzenegger, Jean-Claude Van Damme and Dolph Lundgren have talked about continuing to play ''tough guys'' as they met fans and spoke to reporters on the red carpet at the London premiere of The Expendables 2.

The sequel to Sylvester Stallone's 2010 action film about a team of mercenaries is released in the UK on Thursday.

It sees Stallone joined by a host of 1980s action stars for a revenge mission.

Schwarzenegger told reporters he was ''happy'' to return to film-making following the end of his seven-year tenure as governor of California.
