ABC’s Castle will feature a Comic-Con type episode this fall, guest-starring Star Trek: Deep Space Nine’s Armin Shimerman.
The episode will be directed by Star Trek: The Next Generation‘s Jonathan Frakes.
In the episode, Shimerman will appear as Benjamin Donnely, a “tech geek who manufactures authentic props for costumers at sci-fi conventions.” The tech geek is a “little too eager to show Beckett (Stana Katic) how all his guns work.”
Firefly‘s Nathan Fillion, who appears as Richard Castle in the series joins Beckett at the convention to investigate the murder of a fan. They meet up with former sci-fi star Gabriel Winters (Ed Quinn), who spends days at conventions and nights “having drunken one-night stands” after his “cult-favorite” show Nebula 9 was cancelled.
The Comic-Con episode will air later this fall. Castle, currently in its fifth season, can be seen on ABC Monday nights at 10 PM.
