7. Mary Wiseman
Mary Wiseman reprises her role as Sylvia Tilly from Star Trek: Discovery in Starfleet Academy, although reportedly in a minor role compared to her former Discovery castmates Tig Notaro and Oded Fehr.
It's clear Wiseman loves the franchise, and the actress said of being a part of Star Trek’s nearly 60 years of existence: “I’m so grateful and so honored to get to be a part of it, and so happy to get to continue to be a part of the family."
"I'm just thrilled and really grateful," Wiseman added. Hopefully, Wiseman will have more to do than just appear in a cameo, but we will have to wait and see until the show premieres on Jan. 15. Don't waste her acting talents, please. Wiseman more than proved what she is capable of on Discovery.
