That role led to a small part in Working Girl (1988) and regular spots in Hollywood films such as Flatliners (1990), Indecent Proposal (1993), A Time to Kill (1996), Bulworth (1998) and Doctor Dolittle (1998). The new millennium brought the chance to star in the television series "Deadline" and a recurring role on "The West Wing."
Other notable achievements for Platt include standout turns in Hope Springs (2003), Kinsey (2004) and The Ice Harvest (2005); a Tony nod for his Broadway debut in "Shining City"; and an Emmy nomination for the Showtime series "Huff."
