Fillion fills ‘Buffy’ role

Whedon to work with 'Firefly' actor for series' final segments

Nathan Fillion is joining the cast of “Buffy the Vampire Slayer,” taking on a key role in the final five episodes of the about-to-wrap skein. Fillion, who most recently toplined “Buffy” creator Joss Whedon’s short-lived Fox drama “Firefly,” will play Caleb, a former man of God who’s turned to the dark side and now follows a “Buffy” baddie known as the First. Fillion’s first seg airs next month.

“Nathan Fillion has a leading man’s looks, but he’s actually horribly evil, so he makes Caleb the epic foil for Buffy that he needs to be,” Whedon said. “Caleb calls himself a preacher, but his habit of murdering girls and his alliance with the darkest evil known to man makes him exactly the sort of guy whose ass Buffy needs to kick.”

Whedon also said he was happy to be reunited with the actor.

“Nathan can combine the darkest insanity with the driest wit, and that’s why I like to have him around,” he said.

Thesp’s feature credits include “Saving Private Ryan” and “Blast from the Past.”

Whedon last month confirmed that this season will be the final one for “Buffy,” which has aired on UPN for the past two seasons and previously spent five years at the WB. Series finale of the cult fave will air in May.

Fillion, who’s also working on a pilot for NBC, is repped by Gersh and 3 Arts Entertainment.
