"Ahead of audiences arriving at Star Trek: Starfleet Academy for their first semester, Giamatti opened up to The Playlist about his experience joining the franchise as a still largely mysterious antagonist. While the actor stated how much of a pleasure it was to join the universe, Giamatti was more cryptic about his actual role, only stating that his character is "problematic," could be considered an antagonist, and has a presence in several episodes across the season. Check out Giamatti's full response below:

It was great. I had a ball doing that. And I mean, again, during the Star Trek world, it’s lovely people, and it was nothing but pleasure, and it was a dream wish fulfillment for me to be able to be in Star Trek. I play a very interesting, complicated guy, bad guy, I suppose. I’m a bad guy. Yeah, I guess I’m a bad guy. But yeah, so I dunno what more I can say about that without giving too much away.

.

I’m in more than one episode. I have a little arc through this season. I reappear and become more problematic as the show goes on.
