This Thursday saw the official retirement of one of the greatest Sci-Fi legends of all time. Leonard Nimoy – known mostly for playing the Star Trek character of Spock, hung up the pointy ears once and for all as his final on-screen performance coincided with the season finale of Fringe. Although this weekend will probably be occupied by your inner Losty, why not take a break from the mysteries of the island and pay homage to the great Leonard Nimoy by watching some of his memorable cameo appearances? Waste this weekend with Leonard Nimoy Guest Roles.

William Bell – Fringe Season 1 Episode 20 “There’s More Than One Of Everything”, Season 2 Episodes 10 “Grey Matters”, 22 and 23 “Over There”

The final curtain call for Leonard Nimoy came on Thursday, May 20 2010 as he played his last television character, Dr.

William Bell on the Fox hit Fringe. Although Nimoy made only a handful of appearances on the actual show (including just his voice in some episodes), the existence of his character was integral for the first two seasons. Dr. Bell created Massive Dynamic, a technology-based company that always seems to have their hands in something strange. Bell himself had been traveling back and forth between universes hoping to stop an eventual war. Although this peace-keeping tactic proved successful for a while, the universe crossing made the molecules in Bell’s body unstable. In Nimoy’s final on-screen appearance he helped the main characters return to our universe by sacrificing his body. Kind of a perfect way to go out as Nimoy’s body disintegrated very similarly to that of ‘beaming’ in Star Trek.

Himself – The Simpsons Episode 71 “Marge Versus The Monorail”

In one of the most memorable episodes of The Simpsons ever produced, Leonard Nimoy’s voice almost didn’t make an appearance. Known mostly for the catchy monorail tune, the episode titled Marge Versus The Monorail provided not only great comedy, but a an overall high entertainment value. In the episode, Springfield unveils a brand new monorail and the maiden voyage is supposed to carry a celebrity. Simpsons writers originally cast George Takei, as he’d voiced Simpsons characters before, but after learning that the episode was satirically making fun of public transportation, Takei declined (Takei is part of the board of directors of public transportation in California). Instead, the writers approached Nimoy who accepted the role and became part of a cultural phenomenon.

Galvatron – Transformers The Movie (1986)

Although Nimoy never actually voiced a Transformers character on the animated television series, he played a major role in the 1986 cultural hit Transformers: The Movie. Playing the voice of Galvatron, Nimoy became the ultimate enemy for Optimus Prime and the Autobots. After being defeated yet again by the Autobots, Megatron approaches the powerful Unicron and is given the powerful new body of Galvatron. Galvatron then goes on to wreak havoc on the world of the Autobots and looks to bring ultimate destruction, until his creator, Unicron turns into a planet sized robot and devours him. Nimoy’s voice is not only synonymous with Star Trek lore, but also Transformers.
