(Born July 17, 1976) "The Count Of Montecristo" could have never truly worked as well as it did without a woman so stunning, so attractive both in terms of her physical appearance and her personality as Mercedes so as to convince the audience a man would pull the ultimate betrayal on his best friend just to have her. In Dagmara Dominczyk, director Kevin Reynolds found the perfect woman to pull this off. A Polish beauty who got her first break on the Broadway stage, Dagmara played small roles in "Rock Star", "Keeping The Faith" and "They" before her most famous role in "The Count Of Montecristo".
