Well, most of their own stunts!
They would've done them all had the lawyers not been up their booties about risking stars' lives! LOLz!
"I had a double for when I jumped off of the thing and getting hit by a car the second time. They kinda ratcheted me up from the car, but I'm not afraid to use a double."
LOLz! If you didn't, they'd be out of a job!
Here's what The Rock said:
"We both have great stunt doubles, but with a movie like this, the authenticity was important, so we were down to do our own stunts and it's not a stunt-heavy movie to begin with, it's more character-driven. But when it required me to jump three, four stories off the building—bring in the stunt man."
What, a four story drop isn't your thing, Dwayne??
Ha! The movie looks INTENSE no matter who is doing what, so we don't even care!
