Jack Quaid and Sophie Thatcher break down that wild “Companion” ending

Warning: This article contains spoilers for Companion.

Jack Quaid will "never again" look at an automatic wine opener the same after that wild Companion ending.

Writer-director Drew Hancock's twisty romantic thriller pulls no punches — or wine corks — all the way through the end, as newly-empowered android Iris (Heretic's Sophie Thatcher) fights for her life, both figuratively and literally. After making the world-shattering discovery that she is not a human but rather a robot controlled by her selfish boyfriend, Josh (Quaid), the betrayals just keep on coming. Not only was Josh never really in love with her, but he was also planning to frame her for murder so he could steal $12 million in cash from his ex's new boyfriend, Sergey (Rupert Friend).

But Josh isn't exactly an evil mastermind, and Iris gets swift revenge on him and all his self-centered friends. After she figures out how to change her own settings, she increases her intelligence and aggression and locks Josh out of her controls. She then proceeds to shoot and kill his buddy Eli (Harvey Guillén) before outsmarting his robot boyfriend Patrick (Lukas Gage), who ends up powering himself down after murdering Josh's accomplice, Kat (Megan Suri). Iris finishes the job by uncorking Josh's brains with an automatic wine to the temple.

"It's one of the most creative ways I've ever died in something," Quaid tells Entertainment Weekly. "That was a particularly crazy day because it was our final scene that we shot, and it was so funny to die in that way and then have everybody clap as the movie was over."

He adds with a laugh, "It was really great. It was very cathartic and very cool. It would've been anticlimactic if we ended with anything else, so that was really fun."

Thatcher also loves how the movie ends with her character gaining "total self-control" after saving a robot technician from Empathix, the company that created her. However, filming the scene where Iris kills Josh was "kind of blur." They shot it at 5 a.m., at the very end of production, and everyone was "loopy" on set.

"It was the very last thing, so there was something very satisfying about it," Thatcher says. "But then also, naturally, I was so f---ing exhausted, and I think I had three [cans of] Celsius. It did feel kind of out of body. It added to the madness of it all."

An earlier version of the script had that death-by-wine-cork moment happen much earlier in the movie. "That was originally how Iris was going to kill Sergey — he brings down a bottle of wine, and she uses that to kill him at the very beginning," Hancock tells EW. "And when I got to the part where she needed to kill Josh, I was like, 'F---, I'm not going to be able to top the wine cork thing.'"

The filmmaker knew that the wine cork death needed to be at the end of the movie, so he went back to the drawing board to figure out Iris' first murder.

"I was like, 'Wait, what if I just switched it and just make [Sergey's death] be a pocket knife?'" Hancock says. "Switching that to a pocket knife was perfect — then Jack could be complicit in the planting of the knife, so it all worked out. When you watch the movie, you can actually see the moment where he puts the pocket knife in her pocket."

Keep your eye out for that on your next viewing — Thatcher definitely will: "I've only seen the movie once, and now I need to see it again."

Companion is now playing in theaters.
