In the wake of Leonard Nimoy’s death, stars like William Shatner, to Patrick Stewart, and Spock successor Zachary Quinto have come forward to remember the Star Trek legend. On Sunday, Syfy will pay their tribute to the genre titan with a five-hour programming block.

Starting at 9 a.m. and running until 2 p.m., the channel will feature Nimoy’s appearance in the original Twilight Zone, his two-episode arc on Star Trek: The Next Generation, and the final original cast Star Trek film, Star Trek 6.

Nimoy died Friday at his home in Los Angeles of end-stage chronic obstructive pulmonary disease. He was 83.
