Matt Mitovich of TV Line reports that original trilogy veterans Carrie Fisher and James Earl Jones will be guest starring on an upcoming of The Big Bang Theory. The news was revealed by the show's executive producers during a Golden Globes red carpet interview earlier this evening. Both Jones and Fisher will be playing themselves, and the two will cross paths with Sheldon.
Given how profoundly Sheldon reacted to being given a napkin with Leonard Nimoy's DNA on it, I can only imagine how he'll react to meeting two geek icons. Perhaps by saying... oh goody, oh goody, oh goody!
There is not yet any word on when this episode will air, but it should be sometime in the next few months.
