Ulrich Thomsen's professional journey began with his graduation from The Danish National School of Theatre and Contemporary Dance in 1993. This marked the start of his illustrious career, which saw him take to the stages of various Copenhagen theaters, including Dr. Dantes Aveny, Mungo Park, and Østre Gasværks Teater.
His foray into the world of film began with a role in Ole Bornedal's Nightwatch in 1994. This was followed by a string of notable performances in a range of films, including Thomas Vinterberg's The Biggest Heroes in 1996, Susanne Bier's Credo in 1997, and Anders Thomas Jensen's Flickering Lights in 2000.
However, it was his role as Christian, the son, in Thomas Vinterberg's The Celebration in 1998 that truly catapulted him to international recognition. This standout performance earned him a reputation as a talented and versatile actor, paving the way for him to take on a wide range of roles in the years that followed.
Some of his most notable post-Celebration roles include a villainous part in the James Bond film The World Is Not Enough in 1999 and a role in the English film Killing Me Softly in 2002.
