"The Big Bang Theory" has landed one of its nerdiest guest stars yet. "Castle's" Nathan Fillion is set to appear as none other than himself in the Feb. 19 episode.

《生活大爆炸》已经有了新客串演员了。《灵书妙探》男主Nathan Fillion将会在2月19日的那一集以自己的现实身份出现在剧中。

According to Entertainment Weekly, Fillion -- who also played Captain Malcolm Reynolds on "Firefly" -- will be spotted eating in a restaurant by Leonard (Johnny Galecki) and Raj (Kunal Nayyar), who can't decide if he's the real deal or simply a lookalike. That won't stop them from bugging him for a photo, though.

据《娱乐周刊》报道，在《Firefly》中出演的Captain Malcolm的Fillion将会被看到跟Leonard和Raj在餐厅吃饭，Leonard他们不知道自己看到的是真人还是人有相似。不过这不能阻止他们想要跟他合照。

Considering how big a fan Sheldon (Jim Parsons) is of "Firefly," he's bound to be devastated about missing meeting his on-screen hero. At least he was there when Summer Glau made a cameo as herself in Season 2.

Sheldon剧中是《Firefly》的铁杆粉丝，他肯定会因为没有见到自己超喜欢的荧幕英雄而沮丧。第二季他没见到Summer Glau的时候也是这样。
