‘Firefly’ and ‘Castle’ star Nathan Fillion is to make a brief guest appearance in a forthcoming episode of ‘The Big Bang Theory’.
According to Entertainment Weekly Fillion will be playing himself, eating at a restaurant when Leonard (Johnny Galecki) and Raj (Kunal Nayyar) spot him.
Leonard and Raj then talk among themselves, wondering if they should ask for a picture with him.
The episode is scheduled for February 19 in the US. The series also airs on E4 in the UK, but at present the show is on a break while the channel shows new episodes of ‘Two Broke Girls’.
