The Alamo Drafthouse theaters held six "Mondo Mystery Movies" in Los Angeles this past weekend, and they had different artists create limited edition posters for each of them. One of those artists was Charlie Adlard of Walking Dead fame, who created the above poster for 28 Days Later (with title treatment from Jon Smith).
There's also a variant edition -- same poster, different title treatment -- after the jump, along with the other movie posters they released for Iron Giant, City of Lost Children, Hellraiser, Assault on Precinct 13 and The Mist.
