Even Star Trek: Discovery's cast wants Patrick Stewart on the show

Capt. Jean-Luc Picard, unfortunately, is busy with his own project.

Ask Mary Wiseman, who plays Cadet Sylvia Tilly on Star Trek: Discovery, which Star Trek alumni she wants on the show, and she doesn't hesitate.

"Patrick Stewart," she spits out.

Now playing: Watch this: What Star Trek character would you like to see on Discovery?

She may not even need Capt. Jean-Luc Picard to show up -- just the man who plays him would be fine. Stewart is "my favorite actor," she said.

She's not alone. Wilson Cruz, who plays Dr. Hugh Culber, says the cast was "out of our minds excited" about Picard getting his own series.

Even co-executive producer Heather Kaden is a fan of the idea of bringing Picard to Discovery.

Unfortunately, both Kaden and fellow executive producer Alex Kurtzman shot down the possibility, noting that Picard is in a different timeline. Still, having Stewart back in the Star Trek fold could make it a lot easier. And it's not like time travel doesn't exist in Star Trek, right?

Who else do the cast members want to see somehow appear on Discovery? Sonequa Martin-Green, who leads the show as Michael Burnham, said she wanted to meet Capt. Benjamin Sisko from Star Trek: Deep Space Nine and Capt. Kathryn Janeway from Star Trek: Voyager.

Doug Jones, who plays Saru, said Spock was his favorite character.

"He was the tall skinny one who doesn't look like anyone in the bridge, and I get that," he quipped. But with new cast member Ethan Peck taking on the role of Spock, Jones suggested a villain like Khan Noonien Singh.

"What would Khan have been like back then?" he asked. "Maybe a teenager who hadn't found himself yet?"

Discovery returns Jan. 17 on CBS All Access. (Disclosure: CBS All Access is owned by CBS, the parent company of CNET.)
