According to Moneymaker, Berry's star status and prolific career did nothing to dampen her enthusiasm for putting in the work necessary to appear in an action extravaganza like John Wick 3. In fact, the stunt performer calls Berry the most up-for-it actor with whom she's worked. 

"Most of my actors have been fairly gamed to do stuff, but my number one would be Halle Berry, because I trained her for John Wick 3 and we trained together for six months," Moneymaker says. "She went through more than I can even mention here, but [she] was, no matter what, 100 percent in the role, in the character."

Still, as enthusiastic as Berry was for the type of physical work required in the world of John Wick, there were some things even she couldn't do. As Moneymaker relates it, this typically had to do with issues of safety, and moments when her canine co-stars (Berry's character rolls with two Belgian Malinois) had to be taken into consideration. 

"There were only two parts that Halle didn't do," says Moneymaker. "One was a slide under the table because she could potentially cut her face and we didn't want her to do that, and the other was a dog jumping off her back. It was just because one of the dogs that was supposed to jump off her back wasn't able to make the jump that day, and we had to put a very aggressive dog in. It was just a matter of, 'Oh, if for some reason that dog got freaked out and bit her, we didn't want that to happen."
