Local filmmaker Matt Osterman wanted to make a low-budget, high-concept sci-fi supernatural genre film. Still in the making, Phasma Ex Machina — about someone who invents a machine that can make contact with ghosts — has already captured an international buzz on the Net through an enticing, well-made trailer. 3-Minute Egg met Osterman and the film’s leading actor, Sasha Andreev, during some touch-up scene work at a home in South Minneapolis. The film is now in post-production. A release date hasn’t been set.
