This year, for the third year in a row, Conan will be taping a week of episodes live from San Diego's Comic-Con.
Earlier this week, show host Conan O'Brien celebrated the upcoming trip by welcoming back stand-up Comic Khan (as portrayed by Conan writer Andres du Bouchet) for some Con-appropriate comedy.
Now, he's revealed the lineup of guests expected to appear during his week at Comic-Con -- well, most of them, since there's still one mysterious movie cast that's TBA.
Here's who will join O'Brien in San Diego, according to Deadine:
