A graduate of L'École Claude Mathieu (Paris) and The Lee Strasberg Theater Institute (New York), William Abadie was honored with a Life Time Membership at the famed Actor Studio in 2000. Two years later, during the run of his self-produced Off-Broadway production of Dennis McIntyre's MODIGLIANI (2002), William received positive reviews from the New York Times Theater Critic, Anita Gates. This milestone allowed him to attract established representation, which quickly led to his professional Film and TV career in the U.S. William portrayed memorable characters in some of America's most acclaimed and iconic TV shows: SEX AND THE CITY, THE O.C, E.R, ENTOURAGE, UGLY BETTY, 90210, GOSSIP GIRL, and most recently, the Golden Globe award-winning show HOMELAND to name a few.
