Both Tyrese Gibson and Dwayne Johnson came on set to be part of the action, which involved flying on top of a car door and redirecting a torpedo on the ice.
A. Gill: We had a 40ft-long table on the back of a tow vehicle and put a [stunt] double on it and did a bunch of tows with him. Then we put Tyrese on it. Tyrese came out for two days, and we were towing him at 35-40mph and he loved it.
Razatos: [Tyrese] literally couldn't even see. He'd sit there and we had to have hand signals and everything. He was an amazing trooper on that. He didn't like the cold -- he made sure we knew that. But he did it, and did it as many times as he had to do it. He even offered to stay another day if he had to.
A. Gill: We actually dragged a torpedo on top of the ice and had [Dwayne Johnson] get out of the car, lean down, grab the torpedo, and slide it into that other car which blew up. All of that [was] practical.
Razatos: Visual effects said we'll put in a torpedo, and I said I want to at least try it with a real prop as a torpedo. Trying to do that on a frozen lake at 50mph was quite a challenge but we made it work.
