Stallone has praised Statham in a recent interview for being ‘cool’ after a stunt on the set of The Expendables 3 went wrong.
Statham was shooting a scene on a truck in Bulgaria when it careered out of control into the Black Sea.
Sly said it was ‘unbelievable’ how Statham managed to save himself.
He told Metro.co.uk in an exclusive interview for his forthcoming film The Escape Plan: ‘We had a scene where a truck went out of control and Jason Statham went to the bottom of the river.
‘If all the Expendables had been on that – we were supposed to be on it a minute later – it could have been fatal.’
He praised Statham’s professional behavior after he managed to escape from the vehicle.
‘The truck went to the bottom of the river taking the camera crew and the camera crane,’ Sly said.
‘We lost a million dollars of equipment in a moment and Jason was unbelievable because he’s in heavy boots and swam to the top.
‘He was cool. He cleaned off. A lot of people would have said, “I’m done”.’
Stallone added: ‘I’m just telling you how dangerous this is. This isn’t a little going into a pond. This was off a 12 foot pier, five foot to the bottom.’
