The initials in the title of this ensemble sitcom stood for Assistant United States Attorney. This was the job description of the series' protagonist, Adam Sullivan (Scott Foley). As a novice Federal Prosecutor in New York City, the wide-eyed Adam thought he was prepared for nasty perpetrators, tough opposing attorneys, and intractable judges. What he wasn't prepared for was the sarcastic animosity of his own boss, Geoffrey Laurence (Peter Jacobson), or the fact that his former girlfriend, Susan Rakoff (Amanda Detmer), was one of his principal antagonists, a legal aid lawyer. Other regulars included Ana Ortiz as streetwise A.U.S.A. Ana Rivera, Eddie McClintock as Adam's dippy best friend, Owen Harper, and John Ross Bowie as eccentric paralegal Wally Berman. Created by Richard Appel, himself a former paralegal, A.U.S.A. premiered February 4, 2003. ~ Hal Erickson, Rovi
