Magnet Releasing has crapped out a red-band trailer for Bad Milo, a horror-comedy from the Duplass Brothers, starring Ken Marino (“Childrens Hospital”) as a man who discovers an anxiety-driven demon living inside his intestines.

Things really start to stink when, at his therapist’s urging, he releases the demon, names it Milo and attempts to regain control of his life.

Bad Milo co-stars include Gillian Jacobs (pictured), Patrick Warburton (“Seinfeld”), Mary Kay Place (“Big Love”), Stephen Root (Office Space), Peter Stormare (Undocumented) and Diana Toshiko (Zomboobies). The film drops on VOD on Aug. 29 and in selected theaters on Oct. 4.
