Paul McGillion (Dr. Carson Beckett) is filming a guest-starring role in the fifth episode of Supernatural’s fifth season, entitled “Fallen Idols”. Paul plays the role of Jim Grossman. We don’t know much about his role, but we do know his fellow co-star in the episode will be famous socialite Paris Hilton! Regarding Hilton’s role, from this article:

“We wrote the role just for her,” producer Sera Gamble said. “We’re very excited that she said yes. She plays the role of a demonic creature that takes the form of Paris Hilton. If you know our style, you know we go pretty funny and irreverent with this stuff, so expect that. The fact that she wanted to do the episode speaks volumes about her sense of humor. She’s flat-out awesome for playing along. You’ll see.”

The episode is expected to air on October. 8, 2009, on the US CW network.
