Magnet has released the red-band trailer for director Jacob Vaughan’s horror comedy Bad Milo.  The film stars Ken Marino as a man whose severe gastric problems are the result of an anal demon brought on by stress at work and at home.  We previously saw a green-band debut trailer for the film, but this new one doesn’t hold back on the blood, gore, and graphic colonoscopy footage; if you've been holding your breath for a movie about an evil butt demon, then this film is right up your alley.  Bad Milo looks batshit crazy in a very good way, and Matt caught the film at SXSW and called it “juvenile and totally hilarious.”  Read his full review here.

Hit the jump to watch the red-band trailer.  The film also stars Gillian Jacobs, Patrick Warburton, Mary Kay Place, Stephen Root, and Peter Stormare.  Bad Milo will be released on VOD on August 29th and hits theaters on October 4th.
