“Once we saw RADDOG, we wanted it as member of the crew,” says Charles Wachter, Stars on Mars executive producer and showrunner. “Lost in Space had their robot, Star Wars had their R2D2, and similarly, RADDOG was a big part of our cast. It performed both a functional role in the series—as sentry security for the crew, with remote viewing, and also as a companion. It has a ton of personality, but even more capabilities.”
