Alamo Drafthouse presented 6 Mondo Mystery Movies to Los Angeles audiences this past weekend. For these popular series, which regularly sell out, audiences buy tickets and a poster to screenings of films that remain a mystery until the actual event. If you plan to be in Austin, TX, on October 29 you can get tickets to the next Mystery Movie series here starting today. Posters from this past weekend's screenings are below. Screenings included 28 Days Later (poster by Charlie Adlard of The Walking Dead fame with title treatment by Jon Smith), Hellraiser (poster by Florian Bertmer), The Iron Giant (poster by Kevin Tong), Assault on Precinct 13 (poster by Tyler Stout), City of Lost Children (poster by Ken Taylor) and The Mist (poster by Daniel Danger).
