Actor Grant Masaru Imahara (October 23, 1970 – July 13, 2020) was an American electrical engineer, roboticist, and television host. He was best known for his work on the television series MythBusters, on which he designed and built numerous robots and specialized in operating computers and electronics to test myths. Prior to his television career, Imahara worked at Lucasfilm in the THX division as an engineer and in the Industrial Light and Magic division in visual effects.
Imahara also appeared on the television show BattleBots, for which he designed and competed with his robot Deadblow and later returned as a judge. Imahara starred in the 2016 Netflix series White Rabbit Project alongside his MythBusters co-stars Kari Byron and Tory Belleci.
One of Imahara’s independent projects, during early 2010, was constructing a robotic sidekick for Craig Ferguson, host of The Late Late Show. The robot, named Geoff Peterson, was unveiled on the April 5, 2010 Late Late Show episode and is controlled and voiced by comedian and voice actor Josh Robert Thompson.
Imahara portrayed Hikaru Sulu in all 11 episodes of the web series Star Trek Continues. This the only project of his that I have seen and I think that he did a fine job. He also played Lt. Masaru in the 2015 fan movie Star Trek Renegades. In 2014, Imahara appeared in a series of videos showing the behind the scenes process of how several McDonald’s foods are made. In 2015, he appeared in the TV movie Sharknado 3: Oh Hell No! In December 2016, Imahara became engaged to his long-time girlfriend, costume designer Jennifer Newman.
