Tasha Yar actress recalls what she thought was her last day on 'TNG' for new Star Trek docuseries

As part of the big 55th anniversary of the Star Trek franchise this year, History Channel is airing the 10-part docuseries produced by The Nacelle Company, The Center Seat: 55 Years of Star Trek.

Directed by Brian Volk-Weiss (The Toys That Made Us), the series is overflowing with first-hand accounts from the cast, crew, and creatives from all corners of the Trek universe. The first episode is already available on History Channel with new episodes dropping the next three Fridays at 10/9c.

SYFY WIRE has an exclusive excerpt from the docuseries featuring actress Denise Crosby, who played Security Chief Tasha Yar in the first season of Star Trek: The Next Generation. Below, she talks about her exit ad-lib in "Symbiosis" that was kept in the final episode:

Of course, Crosby returned to The Next Generation to play Yar in the Season 3 episode, "Yesterday's Enterprise." And she came back as Sela, the half-human/half-Romulan daughter of Yar in Season 4 and Season 5. She also went on to document the Trek fandom as a co-producer in her own films, Trekkies (1997) and Trekkies 2 (2003). 

Along with Crosby, the docuseries also includes a huge list of other Trek greats participating including Nichelle Nichols, Brent Spiner, Kirstie Alley, Walter Koenig, Kate Mulgrew, Wil Wheaton, John De Lancie, Nicholas Meyer, Ronald D. Moore, Brannon Braga, Nana Visitor, Robert Picardo, Penny Johnson, Ethan Phillips, Diana Muldaur, Nicole de Boer, Roxann Dawson, Robert Beltran, Tim Russ, John Billingsley, John Dykstra, D.C. Fontana, Rick Berman, and F. Murray Abraham. 

Along with the four episodes available on History Channel, six additional episodes will also be available on HISTORY Vault, the network’s subscription video service.
