Nathan Fillion to guest star on The Big Bang Theory

Nathan Fillion will make a cameo appearance in an upcoming episode of The Big Bang Theory, according to an exclusive report. The Castle and Firefly actor will feature in the February 19 episode of the show as himself. In the episode, Raj and Leonard will see him a restaurant and will debate whether or not it's really him and if they should approach him for a picture.

Firefly, the space western TV series in which Fillion starred, has frequently been mentioned on The Big Bang Theory. Sheldon originally stipulated in the roommate agreement that Friday nights should be reserved for watching Firefly, and he ranks FOX owner Rupert Murdoch alongside Darth Vader as a heinous traitor for the network's cancelling of Firefly. Fillion's Firefly co-star Summer Glau appeared as herself in "The Terminator Decoupling".
