Rob Lowe as KFC’s newest colonel Sunday

Rob Lowe as KFC's newest colonel Sunday

The actor has played many roles through the years — as Sam Seaborn in “The West Wing” and Chris Traeger in “Parks and Recreation,” for example — but the former Brat Pack member who also starred in “St. Elmo’s Fire” is branching out into fast food.

Lowe will portray Colonel Harland Sanders beginning Sunday, donning the colonel’s white suit, black string tie and trademark goatee — but he also will be wearing a space suit, USA Today reported.

Lowe, 53, will be promoting KFC’s Zinger chicken sandwich, the restaurant chain announced Friday.

“My grandfather was the head of the Ohio chapter of the National Restaurant Association in the 1960s and took me to meet Colonel Harland Sanders when I was a kid,” Lowe told USA Today. “It was a big deal. I thought this would be a nice homage to both Colonel Sanders and to my grandfather.”

Among the other seven celebrities who have portrayed the founder of the Finger Lickin’ Good chicken are Darrell Hammond, Norm Macdonald, Jim Gaffigan and actors George Hamilton and Billy Zane.

Lowe, 53, has previously done commercials for DIRECTV.

The spicy Zinger sandwich will debut Monday in the United States after a 33-year stint overseas, KFC said. In a video promoting the sandwich, Lowe steps to the podium in his space suit and proclaims that “The time has come to explore beyond our known horizons.”

Lowe ends the video by asking, “Can you actually launch KFC’s world-famous Zinger chicken sandwich into space?”

His answer? “We certainly hope so. Our entire marketing campaign depends on it.

“But when we succeed, we will lick our fingers. We will lick our fingers good.”
