Mark IRL
Mark Harelik appeared in a ton of TV shows before landing his short-lived role on TBBT. He played David Lynch in 1993’s Wing for five episodes, Ben Hildebrand in Jurassic Park III, and even played God on the AMC TV series Preacher.
Apart from acting in front of cameras, he’s also heavily invested in his career as a writer. He helped playwright Search and Destroy and Cherry Orchard in 1990. However, as of late, he’s stayed away from the spotlight, at least for the time being. His most recent most notable role was Hank Greenberg in 2017’s Battle of the Sexes.
