He has short hair, no stubble to speak of, and a blunt nose. Matt Damon, at least in the “Bourne” series, looks like a bullet. And that's exactly what the insurance company is trying to avoid.Matt Damon as Jason Bourne in Paul Greengrass’s movie. If Tom Cruise gets hurt doing a stunt, the movie gets delayed and the studio will get a pay out due to the delay.

It's usually the insurance company that makes the determination of what the stars of a movie can do. While it's not specified here, the 'safety guy' likely worked for the company that was insuring the production of Mission: Impossible - Ghost Protocol. I’d been dreaming of this stunt for years and I went to the safety guy and I explained what I was going to do and the guy said it was too dangerous.' He goes, 'So I got another safety guy.' I was like, ‘Can you explain how that happened?’ The way he explained it he goes, ‘Well, I went to the safety guy. I talked to Tom Cruise about it about 10 years ago, about the one in Mission: Impossible where he ran outside the building, where he ran down the side of the building.

It’s a magic trick, like how much do you have to do to make the trick work? If it’s really dangerous, they never let us do it. Because of this, Damon once asked Tom Cruise how he was able to do his own stunts such as scaling the Burj Khalifa in Mission: Impossible - Ghost Protocol, and Cruise explained that he did have to make some changes on set so that he could do it, by replacing the guy who wouldn't let him.

Even if he did, there are people and procedures in place on movies to prevent actors from doing things that are considered too dangerous. In a recent appearance on Showtime's Desus & Mero, Matt Damon talked about doing stunts on the Bourne movies, and how he didn't, and didn't necessarily want to, do all the stunts for those movies himself.
