Kevin Sussman as Stuart Bloom – Now:
Kevin worked long before starting "The Big Bang Theory." His prior roles included appearances on "Ugly Betty" and working on the film "A.I. Artificial Intelligence," which Steven Spielberg directed in 2001. Kevin's real life isn't exactly similar to the struggling existence he portrays as Stuart. In addition to his regular work on "The Big Bang Theory," Sussman reprised his role as Steve in the Netflix series, "Wet Hot American Summer: First Day of Camp" in 2015.
