PARK CITY, Utah — Nine years later, Cillian Murphy (KIH'-lee-en) is back at the Sundance Film Festival, where he got such great exposure that people finally learned to pronounce his name.

The Irish actor was a breakout star at Sundance in 2003 with the horror hit "28 Days Later."

The film is about a London man who wakes from a coma to find the land overrun by a plague that has turned people into raging zombies. It was already a hit in Great Britain when it played at the festival.

The rousing reception at Sundance built U.S. buzz for the film and Murphy. He went on to appear in Christopher Nolan's "Batman Begins" and "Inception," and returns to this year's festival with the thriller "Red Lights."
