Castle has had a long running history of Star Trek connections. Earlier this year we saw two new cast members join Castle. Series regular Penny Johnson Jerald (Kasidy Yates Deep Space 9 ) was cast as Captain Gates and Michael Dorn (Worf, ST:TNG and DS9) as a recurring guest playing psychiatrist, Dr Carver Burke.
In the past we’ve had guest appearances by Voyager‘s Robert Picardo as “Doctor Death”, Ethan Phillips (Nelix, ST: Voyager) in the season 3 episode “The Final Nail”, Jonathan Frakes (Commander Riker, ST: TNG) as director of Season 2 episode “Kill the Messenger” and Trek producer René Echevarria was a Writer/Executive Producer for Season 2 and of course, with Castle since the beginning, Rob Bowman who directed many Star Trek: The Next Generation episodes.
In the January 23rd episode titled “An Embarrassment of Bitches“ a famous dog trainer is killed, the investigation keeps coming back to charismatic reality TV star Kay Cappuccio, a favorite of tabloids and gossip websites the world over but there seems to be more to her story than she is letting on.
Among the guest cast for this episode is none other than Star Trek Deep Space 9′s Nana Visitor as Dr. Patty Barker. If there isn’t some kind of Trek reference in this episode, here’s one Castle fan that will be a little disappointed!
Also of note to Sci-Fi fans, the episode is directed by Tom Wright who also directed episodes of Angel, Firefly and the X-Files.

Maybe it’s time for a Body of Proof crossover, would love to see Dana Delany on Castle again (Agent Shaw has a twin sister right?) and it’d be a great excuse to have Jeri Ryan on the show too!
Patrick Stuart. However, if I ever saw Stana, Nathan AND Patrick in the same scene I fear my heart would explode. Simply too much good in one place for a mere human to handle.
Sir Patrick Stewart would make an awesome guest star
Her character’s name is Barker and she’s in an episode where a dog trainer is killed? If there isn’t ALSO a dog reference in this episode, I’ll be pissed. B-)
haha, I didn’t even notice that.
Brent Spiner, people!! I mean, I love me some Patrick Stewart, but Spiner would be AMAZIG!
Jolene blalock would be good for a guest
Brent Spiner all the way! He was really great in Law and Order CI.
Marina Sirtis would be an amazing guest!! She is adored by her legions of fans who would definitely watch eps even if they aren’t already a Castle fan!!!
Oh, great! Sound like leverage…
But star trek is a very long tv series, The cast is a big lot of people!
Castle is a beautiful tv show guest or not!
hmm! We should have William Shatner play a bad corrupt banker/lawyer/corrupt tool who has invested in some artifacts that strangely look like fazzers, and he got them by “any means possible”
I loved Michael Dorn on Castle, first time I heard him (before I saw him) I was like YES!! lol.
Jeri Ryan would be awesome, and not to pretend like I think it’s gonna happen, but Kate Mulgrew *awesome*. Brent Spiner would be awesome too, or John Billingsley.
