While at the blue carpet premiere of Star Trek: Discovery last month, the folks at TrekMovie had the chance to talk to the show's executive producers Aaron Harberts, Gretchen J. Berg, and Heather Kadin regarding how big a role Sarek’s family will play going forward in the series. Although the three couldn't reveal much -- including whether Spock will make an appearance at some point -- Harberts did reveal to the outlet that The L Word actress Mia Kirshner has been cast as Amanda Grayson. The role, of course, was originated by Jane Wyatt in the season two episode of Stark Trek titled "Journey to Babel." The role was later played by actress Winona Ryder in director J.J. Abrams' 2009 reboot.

Along with her work on The L Word, Kirshner has also appeared in Syfy's Defiance as well as the CW's The Vampire Diaries. It's currently unknown in which episode of Discovery Kirshner will make her debut as Amanda.
