Mark Wahlberg has admitted he's not as reckless as he used to be when filming action stunts, as he's afraid of getting hurt.
The 43-year-old rapper-turned-actor revealed he was a bit freaked out when director Michael Bay asked him to walk a tightrope between two skyscrapers for Transformers: Age Of Extinction.
Mark admitted: "If it's on the ground, that's not a problem, but 20 storeys up, that's pretty nerve-racking.
"Michael was like, 'What's the matter? You're holding onto the wall? I've heard all these stories about you jumping off buildings, jumping out of windows...'
"I was like, 'Dude, that was a long time ago, I have four kids, I'm very successful now. I have plenty of reasons to live!'."
But the father of four - star of Boogie Nights, Ted and The Fighter - also revealed he really enjoyed making a movie he could share with his kids.
"This movie was the first time [my kids] were actually excited about Daddy going away to work," he said.
Three of his four children attended the film's New York premiere with him. "Cut to two hours after and they're trashing the hotel room playing Transformers, waking up my wife, and I had to explain why they're still up at 1.30 in the morning with candy all over their faces.
"It was awesome, it was the first time I got to experience something like that with my children."
:: Transformers: Age of Extinction is in cinemas now.
