Gossip Girl may be over for the season, but Ed Westwick (aka Chuck), is keeping busy. The British actor has just been cast in S. Darko, a follow-up to Donnie Darko, the 2001 cult fave that helped put the Gyllenhaal sibs on the map, says the Reporter.

The Darko sequel will feature the story of Samantha, Donnie’s sister, who leaves town with her best friend in the face of a broken family and strange visions. Daveigh Chase will return as the Darko sis, while Step Up to the Streets 2’s Briana Evigan just joined to play Samantha’s friend. Along with Westwick and Evigan, Elizabeth Berkley has also just joined the film. She’ll play a former drug addict who’s now devoted to Jesus — and to her hunky pastor.

How will the follow-up play out? Anything with Westwick is promising…as long as it doesn’t distract him from his important work on the Upper East Side. — Anna Dimond
