The upcoming Star Trek Beyond has added yet another new cast member to its ranks, but—as is proving to be a pattern with these sorts of announcements—there are no details on who she’ll be playing. Lydia Wilson is best known for her performance as Domhnall Gleeson’s colorful sister in the rom-com About Time; she’s also appeared in some British TV shows like Ripper Street and Misfits. According to Variety, Wilson has officially joined the Star Trek cast, but whether she’ll be aligned with the returning crew of the U.S.S. Enterprise or with Idris Elba’s mysterious villain remains to be seen.
