The director/producer team that created "Trainspotting" turn their dynamic cinematic imaginations to the classic science fiction scenario of the last people on Earth. Jim (Cillian Murphy) wakes up from a coma to find London deserted--until he runs into a mob of crazed plague victims. He gradually finds other still-human survivors (including Naomie Harris), with whom he heads off across the abandoned countryside to find the source of a radio broadcast that promises salvation. "28 Days Later" is basically an updated version of "The Omega Man" and other post-apocalyptic visions; but while the movie may lack originality, it makes up for it in vivid details and creepy paranoid atmosphere. "28 Days Later"'s portrait of how people behave in extreme circumstances--written by novelist Alex Garland ("The Beach")--will haunt you afterward. Also featuring Brendan Gleeson ("The General", "Gangs of New York") and Christopher Eccleston ("Shallow Grave", "The Others"). "--Bret Fetzer"
