In the film Orion, now in theaters, astronaut Apollo (Drew Van Acker) returns to Earth after his crew has been killed in a mission, with no recollection of the events that took place. Interrogated by a man who claims to only be searching for the truth, the two work together to try to piece together his fractured memories. But as Apollo’s memories start to come together, he discovers the terrifying truth that he didn’t return alone, and everyone could be in danger.

Director Jaco Bouwer recently spoke with SciFi Vision about building the layered story of Orion, guiding Drew Van Acker through Apollo’s shifting truths, and maintaining tension in extended conversations between two characters. He also discussed creating an otherworldly atmosphere through production design, camera work and sound, the inspiration behind the alien communication instrument, the scenes he found most rewarding, and more.
