Of Irish and Polish descent, Eric Mabius was born on April 22, 1971. He grew up moving almost constantly. Upon graduating from high school he attended the renowned arts school, Sarah Lawrence College. Immersing himself in acting, writing and film theory, college became the jumping-off point for Mabius' first roles in the theater in smaller Off-Broadway productions. He landed his first film role as the object of Heather Matarazzo's affection, the teen rock star, in Todd Solondz's Sundance Grand Prize Winner, Welcome to the Dollhouse.

Mabius has appeared in more than 27 films - seven of which screened at Sundance - and over a dozen television projects. His credits include roles in many genres, ranging from action (Resident Evil and The Extreme Team), drama (Cruel Intentions), comedy ('Welcome to the Dollhouse' and Wirey Spindell), mystery (The Minus Man), horror (The Crow: Salvation and Black Circle Boys), and romance (Splendor and Dancing at the Harvest Moon). Showtime's groundbreaking series, The L Word and ABC's Eyes are but a few more in a long line of unique and varied projects he has chosen that have achieved critical and audience acclaim.
