I think David Krumholtz is one of the youngest “That Guy”s in Hollywood working today! He began acting at age 13 on Broadway in 1992, and shortly thereafter began acting in feature films, namely Life With Mikey and Addams Family Values – both in 1993. The following year, Krumholtz had a major supporting role as Bernard the Elf in The Santa Clause, a role which he reprised in the film’s first sequel. Since then, Krumholtz has been popping up everywhere, with his film credits including movies such as 10 Things I Hate About You, The Mexican, Tenacious D in The Pick of Destiny, Superbad, Walk Hard: The Dewey Cox Story, the Harold & Kumar trilogy, and Serenity. His TV work includes roles on Freaks and Geeks, ER, Law & Order: SVU, The Playboy Club, and Numb3rs. David Krumholtz turns 34 today.
