If Jack conveys a visual sense of deja vu, it’s probably because fans already know his actor. Joel Johnstone plays Sonya Nikolayevich’s assistant brother, Jack, in CSI: Vegas. And the role of a coroner for a Las Vegas crime-fighting unit only adds to the varied list of appearances and characters in Johnstone’s career. A native of Milwaukee, Wisconsin, he has been an actor for quite some time via DPN Talent. Johnstone’s career began in 2000 with work guest appearances on various TV shows such as Urban Gothic, Ed, and Criminal Minds (via IMDb). The actor got his first big break in Aaron Sorkin’s The Newsroom, where he played Cameron, a young collaborator of Mitt Romney.
In 2015, Johnstone transitioned from political staff to launch under the stars when he played real-life astronaut Gus Grissom on The Astronaut Wives Club. Looking back, that role feels like a foreshadowing from Johnstone eventually finding his way onto CSI. After all, Gil Grissom’s name was apparently inspired by the astronaut’s. After Astronaut’s Wives Club, Johnstone played the recurring role of Archie Cleary on The Marvelous Ms. Maisel.
In addition to his on-screen roles, many players have likely heard his voice as well. Johnstone has worked as a voice artist for games such as Metal Gear Solid V: The Phantom Pain, Final Fantasy Type-0, and Dishonored.
