Leonard Nimoy, who died at the age of 83 on Feb. 27, left behind a long and memorable career of performances that stretched from Earth throughout the final frontier of space.

Much of that work can now be revisited for longtime fans or seen for the first time for those looking to see some of Nimoy’s best work. Here are some of the essential performances that can be found on Netflix, Amazon Prime, and more.

Star Trek
Available on: Netflix, Hulu, Amazon Prime
Nimoy’s most iconic role is, of course, as Spock in the many incarnations of the Star Trek franchise. Thankfully, all three seasons of the original series that made Spock and the Vulcan Salute household names can be found on most major streaming services. For one of Spock’s best outings, try season two’s premiere, “Amok Time;” it’s an incredible example of Nimoy’s work on the show.

Star Trek II: The Wrath of Khan
Available on: Netflix
Several of the Star Trek films are streaming on Netflix—but for many fans, few compare to The Wrath of Khan, the second major film in the franchise. Spock’s climactic death scene is paramount to the movie’s place in the franchise’s history—and while fans have seen Spock since, Spock’s last moments are among the most iconic sendoffs for a character in cinematic history.

Invasion of the Body Snatchers
Available on Netflix, Amazon Prime
Nimoy had a supporting but memorable role in the 1978 Body Snatchers as psychiatrist Dr. David Kibner. He also played his character’s alien double, who in part helps to explain what exactly the aliens’ goals are in the film.

Before Nimoy even appeared on Fringe, his character, Dr. William Bell, played an integral role in the series’ mythology and the history of John Noble’s Walter Bishop. Nimoy first appeared in the season one finale and would occasionally pop up throughout the series, despite his announced retirement from acting during the show’s run. The producers even worked around his retirement in season three with an episode, “Lysergic Acid Diethylamide,” that included animated sequences using only Nimoy’s voice.

Mission: Impossible
Available on Netflix
Nimoy joined the cast of Mission: Impossible in its fourth season and remained with the show through its fifth. Playing The Great Paris, he essentially replaced Rollin Hand on the show, and used his history as a magician to disguise himself on missions. One of his most memorable outings came in season four’s “The Great Falcon,” the show’s only three-part mission.
