He joins the [**previously announced Marina Sirtis**](https://www.londontheatredirect.com/news/marina-sirtis-from-star-trek-the-next-generation-is-set-to-star-in-dark-sublime-at-trafalgar-studios) (*Star Trek: The Next Generation*), who makes her West End stage debut as Marianne. *Dark Sublime* opens at [**Trafalgar Studios**](https://www.londontheatredirect.com/venue/169/trafalgar-studios-2.aspx) **this summer on 25 June** for a limited run.
### A sci-fi geek's dream casting for *Dark Sublime?*
For a brand-new play that is rooted in the sci-fi genre, *Doctor Who*'s **Mark Gatiss** and *Star Trek: The Next Generation*'s **Marina Sirtis** seem like a dream come true for sci-fi fans.
In addition to his work for BBC One's *Doctor Who, *Gatiss is also known for co-creating and starring in BBC One's *Sherlock,* playing the lead in the Nottingham Playhouse revival production of *The Madness of George III,* and for appearing on BBC Two's *The League of Gentlemen*. In film, he most recently appeared in *Christopher Robin, *and his last sci-fi series appearance was on the 2017 animated television series, *Thunderbirds Are Go.*
Mark Gatiss will be lending his voice to *Dark Sublime* to play a hysterical talking computer named Kosley while Marina Sirtis, in a role where art imitates life, will be playing Marianne, a jobbing actress who once starred in a major science-fiction TV show.
Marina Sirtis is best known for portraying *Star Trek *character Troi on *Star Trek: The Next Generations *and its many subsequent spin-off films and series.
Further casting for *Dark Sublime *will be announced in April 2019.
### About the new *Dark Sublime* play

It is directed by **Andrew Keates**, whose previous directorial works at Trafalgar Studios include *As Is *and *Dessa Rose. *The play was originally set to premiere at the Bush Theatre but will now be heading straight to Trafalgar.

It's been years since the series has ended, yet all Marianne is remembered for is her long-forgotten sci-fi role.
