Nathan Fillion to Portray Himself on The Big Bang Theory

at .

Nathan Fillion may play the hot detective on Castle, but to geeks everywhere, he's a hot commodity, as well.

Thanks to roles in series such as Firefly, Dr. Horrible's Sing-Along Blog and Buffy the Vampire Slayer, he's got wicked geek cred. So much so that he's about to drive them wild on The Big Bang Theory – as himself!

That's right, EW first reported Fillion will make a cameo appearance on The Big Bang Theory on the Feb. 19th episode when Raj and Leonard spot the mega star sitting in a restaurant. The two will ponder the viability of the discovery – can it really be Nathan Fillion and should they ask for a photo?

If you're a TBBT fan, you know Sheldon is a big Firefly fan who likes to lament its cancelation. This is sure to put a bug in his bonnet. Will he believe the duo actually met Fillion or would even a photo not prove to be worth a thousand words in this case?

We'll have to wait and watch, but it's sure to be plenty of fun. 

If you're in need of a fix, you can watch The Big Bang Theory online via TV Fanatic.
