Supernatural star Misha Collins will appear on the next episode of Whose Line Is It Anyway? as a celebrity guest star.

Collins, who plays the angel Castiel on Supernatural, will join comedians Wayne Brady, Colin Mochrie, Ryan Stiles, and this week’s rotating chair, Whose Line veteran Brad Sherwood, on the resurrected improv sketch show’s second season. Whose Line Is It Anyway? is hosted by comedian Aisha Tyler.

Collins took to Twitter at the end of May to confirm the news:

Collins has an infamously quirky sense of humor so seems like the perfect fit for the comedy show.

View a handful of promotional stills previewing the episode:

From these stills, it appears that Collins will be taking part in two sketches, as is the case with most celebrity guest stars on the new Whose Line.

We also have a promo for the episode:

Collins, who first appeared in Supernatural‘s fourth season, will be a series regular in the veteran drama’s tenth season, airing this fall on The CW.

At the beginning of May, Collins also released a web series, titled TSA America: Level Orange, with a portion of proceeds going to his charity, Random Acts.

Whose Line Is It Anyway? season 2, episode 9 airs Monday, June 16 at 8:00 p.m. ET on The CW.
