Following in the footsteps of Leonard Nimoy won't be easy, but "Star Trek: Discovery" newcomer Ethan Peck at least has the support of the original Spock's family.

CBS announced Tuesday that the actor had been cast in the role, and he quickly showed that he knows what big shoes he has to try to fill. Peck tweeted a touching message for the Nimoys that was full of gratitude.

"Thanks to the Nimoy family for your open arms, warm welcome, smiling curiosity and support, for making me feel worthy, as I embrace and take into my heart the iconic half alien we know as Mr. Spock," Peck wrote. "It is an incomparable honor."

Peck's tweet shows that the family has embraced him both figuratively and literally; it includes a photo in which he and Nimoy's two children, Adam and Julie, alongside partners Terry Farrell and David Knight, are doing the Vulcan salute. The Nimoy family also shared it via Twitter, and they took the time to add kind messages.

Trekkies' response on Twitter to Peck's casting was mixed, but he'll have the chance to win everyone over soon. He joins a cast that Sonequa Martin-Green, Doug Jones, Shazad Latif, Anthony Rapp, Mary Wiseman, Wilson Cruz, and Anson Mount.

New episodes of "Star Trek: Discovery" will arrive on CBS All Access in 2019.
