Perhaps the most fun Psych viewers have is when the series does an homage episode. The long-running USA mystery/comedy series has taken playful jabs at everything from horror movies and the Police Academy franchise, to Twin Peaks and The Fast and the Furious, and those have been some of the cult show's best-rated episodes.
Equally popular is when The Princess Bride's Cary Elwes appears on the series--so it's obviously going to be met with some excitement this season, when Elwes returns for what appears to be a Harry Potter-themed episode set in London.
"Green Screening with Cary Elwes & Roday. That's right, we bad, we bad...kinda...not really. Psych Season 8," series star Dulé Hill wrote on Facebook, posting the image at right. Fans almost immediately noticed that Hill was dressed in Hogwarts colors and one savvy Facebook friend brought it to the attention of TVLine.
Their response: "You bet your expecto patronum I’ve got light to shed. You see, the guys are going to 'London' at some point in Season 8, so naturally Gus would find a reason to be in a Harry Potter costume, naturally Despereaux would show up (as we already scooped for you), and naturally there will be lots of action (hence the green screen behind them)."
