In Orion, an astronaut, Apollo (Drew Van Acker), returns home to Earth after a catastrophic mission left his crew dead, with no memory of any of the events that took place. In the search for the truth, he must rely on the man interrogating him who he isn’t sure he can trust. But as his fractured memories begin to reemerge, and he starts to piece together what happened, he uncovers the terrifying truth that he didn’t return alone, and they might all be in danger.

Stars Van Acker and Debby Ryan, who plays his wife, Mary, spoke with SciFi Vision about their roles in the film, a contained sci-fi thriller built around shifting truths and layered performances. Van Acker discussed helping develop the film as a producer and preparing to play Apollo across several phases of the story, while Ryan explained how she approached a character whose motives and behavior are gradually recontextualized.

Orion is now in theaters. Watch the full interview below.
