MCU fans may know Luke Hemsworth as the older brother to Thor himself, Chris Hemsworth. But for Westworld fans, Luke will always be Ashley Stubbs, the head of Westworld's Security Force who later became a host himself. In an interview with THR, the oldest Hemsworth brother revealed that his exciting fight sequence with Evan Rachel Wood in the fourth episode of the third season of Westworld had to be majorly reframed to take into account his muscle injury.
"At the time, I didn't [enjoy the fight scene] because I'd ruptured my bicep. My bicep had actually snapped off the bone. So the first fight scene with the guys in the hallway was done when I hadn't had surgery at that stage. And then, I think when I did the one with Evan, I'd had surgery. So my left arm was completely incapacitated in both fights. If you watch early in that first hallway fight, I get shot in the left arm and then I never use that arm again. So that was something we worked into the story. I had to make a very sheepish call to production and say, "I've done this really stupid thing. What are we going to do?" And then, all those fears and anxieties go through your head of, "Well, that's it for me. I'm going to get fired."
Actors getting injured midway through production is a producer's biggest nightmare, even if the injury is not visible, because it interferes with the actor's performance in action scenes. If the actor in question is not the main lead, they can often find themselves replaced rather than the producers waiting for them to heal. In Luke Hemsworth's case, fortunately, he found the Westworld showrunners to be much more accomodating than he had feared.
"[The producers] were very, very concerned and very willing to work that into the story and make something of it. And ["The Winter Line" director] Richard J. Lewis actually said, "Ah, it's better in the end." He said, "The fight was great. You did it one-handed and it looked better than it would've looked two-handed." So yeah, it was nice to be able to use that misfortune in a good way. But it was a hell of a recovery and I don't wish it upon anyone."
Fortunately, Hemsworth's injury ended up helping make the fight sequence better rather than hindering it. As far as the fate of his character is concerned after the brutal beatdown he received at the hands of Dolores, Hemsworth is not ready to provide a definite answer:
"I don't know. Your guess is as good as mine. When Bernard (Wright) woke up, we didn't see if Stubbs was still there or not. Maybe he's melted from acid in the bathtub or something."
The fourth season of Westworld was formally announced on April 22, 2020, by HBO. Considering the difficulty facing Hollywood in getting productions up and running in the current age of social distancing, it is probable that the release of Season 4 will be pushed back to 2022 or later. This news arrives from The Hollywood Reporter.
