Mark Wahlberg insists actors are not ''tough'' for doing their own stunts.

The self-confessed ''adrenalin junkie'' - who was jailed as a teenager for assault - is happy to shoot his own action scenes, but insists those who do are not as ''badass'' as they think.

He said: ''I [do my own stunts[, I was an adrenalin junkie when I was young but it annoys me when actors talk about how badass they think they are doing their own stunts.

''These are the guys who spend an hour in the make-up chair and another hour looking at themselves in the mirror. You wanna see tough? Go to prison.''

Despite being happy to do his own stunts, the actor admits working on 'Transformers: Age of Extinction' was sometimes ''scary'' because of director Michael Bay's desire to push things to their limit.

He said: ''Every day brought something new. You're running along a 19th floor terrace on a ledge. You're on a little wire and, OK, you're not gonna fall to your death, but when you fall you smack up the side of the building and people are throwing stuff at you and you're running and people are screaming and Michael wants you throwing stuff at people.

''It's pretty scary at times.''

And while the crew were thrilled at the thought of using a new type of camera on the movie, Mark was less than impressed because it kept attacking him.

He told Loaded magazine: ''There was a camera rig on my car. It came from Germany and had never been used before.

''The film crew were like, 'It's so cool and it's never been used before'. I'm like, 'Well no, it's a f***ing problem because if it's never been used, they probably don't know how to use this s**t'.

''And I got this camera like a robot that does all these cool moves but the f**ing thing keeps smashing into me. And Michael Bay was like, 'This shot is awesome!' ''
