Vincent Paul Kartheiser (born May 5, 1979) is an American actor. Although he primarily appears in independent films, he is also known for his role as Connor on th TV series Angel.
Kartheiser was born in Minneapolis, Minnesota to Janet Marie Gruye and James Ralph Kartheiser. He has four sisters, Andrea, Colette, Elise and Theresa, and a brother, Nathan. He lists Monica Keena as his favorite actress and has worked with her on two films, Crime and Punishment in Suburbia and Strike!.
Kartheiser made his screen debut with a bit role in the 1993 film Untamed Heart, opposite Marisa Tomei and Christian Slater. Kartheiser found himself cast in mostly family fare, most notably the action-adventure drama Alaska, in which he starred opposite Thora Birch and Charlton Heston (whose son directed the film). The film led to Kartheiser getting the lead role in Masterminds, playing opposite Patrick Stewart.
Kartheiser's next role established his range and capacity to play complicated roles; He played Bobby, a drug-addled, homeless street urchin in Larry Clark's Another Day in Paradise. Among his castmates were James Woods and Melanie Griffith. The film earned the young actor significant accolades, and he went on to appear in Strike! (later retitled All I Wanna Do), opposite Kirsten Dunst, Gaby Hoffmann, and Monica Keena, the last of whom co-starred with him again in his next next project, Crime and Punishment in Suburbia.
Screened at the 2000 Sundance Film Festival, Crime and Punishment in Suburbia was a moody, updated take on Dostoyevsky's Crime and Punishment, set in a modern high school. The film furthered his reputation as a daring performer uninterested in taking the safe route for higher visibility. Kartheiser later landed a regular role on up on the supernatural drama series Angel in 2002. He played Connor, the son of two vampires, Darla (Julie Benz) and the titular Angel (David Boreanaz). Upon returning to L.A, Conner's gradually unraveling mental state was among the main focuses of the show's fourth season (he would make two more appearances during its final season).
Returning to film work, Kartheiser starred in the well-received coming-of-age drama Dandelion, which was shown at the 2004 Sundance Film Festival.
He is currently filming for a show called 'Mad Men'.
