Lone Survivor director, Pete Berg, has revealed that Mark Wahlberg narrowly escaped death on set after a mishap with explosives.

Speaking to Variety, Pete said: ''I did blow him up, by accident. That was close. We almost lost Mark, for real.''

However, this wasn't the only accident that happened on the movie set, as a stuntman was left with three broken ribs and a punctured lung after a failed attempt to jump off a cliff.

Berg added: ''I went up, I'm like, 'What are you going to do? And he said, 'Well, I'm going to run off this cliff, I'm going to leap off it, I'm going to hit that tree, I'm going to bounce off the tree, I'm going to hit a rock, and I'm going to bounce out.'''

Lone Survivor is scheduled for release on January 31.
