Stuhlbarg was born in Long Beach, California, the son of Susan and Mort Stuhlbarg, philanthropists. He was raised as a Reform Jew. He has said, "It\'s more of a spiritual resonance as opposed to particularly of Judaism." Stuhlbarg trained at The Juilliard School in New York City, where he was a member of the Drama Division\'s Group 21 (1988–1992). He graduated from Juilliard with a Bachelor of Fine Arts degree in 1992.\n', '
Stuhlbarg also studied acting at the University of California, Los Angeles, the Vilnius Conservatory in Lithuania, the British American Drama Academy at Oxford, and the National Youth Theatre of Great Britain at the University of London. He also studied mime with Marcel Marceau. Stuhlbarg is married to Mai-Linh Lofgren.\n', '
Stuhlbarg began his career appearing in stage productions. In a 1993 production of Saint Joan, Stuhlbarg portrayed Charles VII of France; however, UPI critic Frederick M. Winship thought that Stuhlbarg was miscast in the production. The following year, he portrayed the title character in a production of Richard II. Writing for The New York Times, theater critic David Richards dubbed Stuhlbarg a "promising young actor", yet felt his portrayal of Richard came across as a "blend of Rasputin and an odious rent collector is altogether unavoidable, but I\'d like to believe it\'s not his fault." He starred in the two character play Old Wicked Songs throughout late 1995. For his role in the 1996 production of the Eugene O\'Neill play Long Day\'s Journey into Night, Stuhlbarg won the Elliot Norton Award for Outstanding Actor in a large company production. In a 1997 production of Henry VIII, Stuhlbarg played multiple roles, including Thomas Cranmer.\n', '
