David Krumholtz (born May 15, 1978) is an American actor best known for playing Professor Charlie Eppes in the television series Numb3rs. He appeared as Seth Goldstein in Harold & Kumar Go to White Castle and its two sequels, Harold & Kumar Escape from Guantanamo Bay and A Very Harold & Kumar 3D Christmas. He is also known for his role as Bernard the Arch-Elf in The Santa Clause and its sequel, The Santa Clause 2. Additionally, he is known for his role as "Mr. Universe" in the 2005 film Serenity.

Krumholtz was born in Queens, New York. He is the son of Judy, a dental assistant, and Michael Krumholtz, a postal worker. He grew up in a "very working-class, almost poor" Jewish family. His mother moved from Hungary to the U.S. in 1956, and his paternal grandparents immigrated from Poland.

Krumholtz began his acting career at the age of 13 when he followed his friends to an open audition for the Broadway play Conversations with My Father (1992). Though he did not expect to get the part, he won the role of Young Charlie opposite Judd Hirsch, Tony Shalhoub, and Jason Biggs, who was also making his Broadway debut. Soon after his run on Broadway, Krumholtz co-starred in two feature films, Life With Mikey (1993) opposite Michael J. Fox, and Addams Family Values (1993) opposite Christina Ricci. For his role in Mikey, David was nominated for a 1993 Young Artist Award. Although his work in these two films garnered him critical attention, David is probably best known by children as the sarcastic head elf Bernard from The Santa Clause (1994) and its 2002 sequel The Santa Clause 2: The Mrs Clause, but due to filming overlap with Numb3rs was unable to take part in The Santa Clause 3: The Escape Clause.^{[citation needed]}
