Star Trek began in 1966 as a TV series created by Gene Roddenberry, and has accounted for five more TV series, as well as 12 feature films—the latest being Star Trek Into Darkness, directed byJ.J. Abrams. In addition to a bevy of quotable lines—“Beam me up, Scotty!” and “Live long and prosper,” to name a few—Trek is also known for its flashy star cameos. From Family Guy creator Seth MacFarlane to Dwayne “The Rock” Johnson and King Abdullah of Jordan, here are the most famous celebs to appear on Star Trek.
The Family Guy creator is a major Star Trek fan and has included numerous references to the series on the show. He made a cameo as Rivers, a human Starfleet officer who served as an engineer on the Enterprise and Columbia NX-02 on the TV series Star Trek: Enterprise. The two episodes he appeared in, “The Forgotten” and “Affliction,” aired in 2004 and 2005.
Ashley Judd was an up-and-coming actress when, in 1991, she starred in two episodes during the fifth season of Star Trek: The Next Generation. Judd played Ensign Robin Lefler, a human Starfleet officer who has a romantic tryst with Lt. Junior Grade Wesley Crusher, played by Wil Wheaton.
Dwayne “The Rock” Johnson
Before he became a movie star in 2002’s The Scorpion King, Dwayne Johnson was an eyebrow-raising WWF wrestler known as The Rock. In 2000, he portrayed the Pendari Champion—a Tsunkatse fighter who defeats Seven of Nine (Jeri Ryan) in her first fighting match—on an episode ofStar Trek: Voyager.
King Abdullah of Jordan
Even royalty wanted to get in on the action. Abdullah bin-al Hussein, then-prince and now king of Jordan, was a huge Trekkie and made an appearance as an uncredited extra in the 1996Star Trek: Voyager episode “Investigations.”
In 1992, Grammer appeared as the bearded Captain Morgan Bateson in an episode of Star Trek: The Next Generation. Bateson is captain of the USS Bozeman and sees his ship get transported forward in time to the 24th century due to a temporal distortion.
Hemsworth was a relatively unknown Australian soap star when he was cast as George Kirk, the father of James T. Kirk (Chris Pine), in J.J. Abrams’ 2009 film Star Trek. George manages to save 800 people in just 12 minutes as captain of the USS Kelvin, after it takes heavy fire from the Romulan ship Narada, captained by Nero (Eric Bana). The role was originally offered to Mark Wahlberg.
Slater appeared in an uncredited cameo role as the night-shift communications officer in the 1991 film Star Trek VI: The Undiscovered Country. The night-shift communications officer served in the communications department of the ship Excelsior under Capt. Hikaru Sulu, played by George Takei.
Ryder played Amanda Grayson, the human mother of Spock (Zachary Quinto), in the 2009 film Star Trek. She is killed when Vulcan is attacked—and ultimately destroyed—by the Romulan ship Narada, captained by Nero (Eric Bana).
Before he hit the big time, Hardy starred as Shinzon, a Romulan clone of human Starfleet Captain Jean-Luc Picard (Patrick Stewart) in the 2002 film Star Trek Nemesis. Shinzon attempts to destroy Earth, but is killed during the Battle of the Bassen Rift.
Before Sex and the City, Cattrall played Valeris, a Vulcan Starfleet officer aboard the USS Enterprise-A in the 1991 film Star Trek VI: The Undiscovered Country. Cattrall received a Saturn Award nomination from the Academy of Science Fiction, Fantasy & Horror Films for her performance.
The former model, and current wife of David Bowie, starred as Martia, a chameloid imprisoned on a Klingon penal colony after a botched attempt to kill Capt. James T. Kirk and Dr. Leonard McCoy in the 1991 film Star Trek VI: The Undiscovered Country.
Seinfeld star Alexander, a devoted Trekkie, made a cameo as Kurros, a spokesperson of a group of alien scholars known as the Think Tank, in a 1999 episode of Star Trek: Voyager. Kurros is probably best known for his unique face, which resembles… take a wild guess.
The director of The Usual Suspects and the X-Men films is also a huge Trekkie, and even flirted with directing the Star Trek reboot (the job ultimately went to J.J. Abrams). He made a cameo as a tactical officer aboard the USS Enterprise-E in the 2002 film Star Trek Nemesis.
Before she became a soap-opera legend, Joan Collins starred as Edith Keeler, a social worker who ran a soup kitchen in the Twenty-First Street Mission on planet Earth, on the original Star TrekTV series. The episode she appeared in, “The City on the Edge of Forever,” aired back in 1967.
Following back-to-back Emmy wins for his role onTaxi, Lloyd transitioned to films and starred as Klingon Commander Kruge, a villain who is out to acquire the technology to terraform an entire planet, in the 1984 film Star Trek III: The Search for Spock.
