He has since played both leading and supporting roles in films such as Beetlejuice (1988), The Hunt for Red October (1990), The Marrying Man (1991), The Shadow (1994), Notting Hill (1999), The Aviator (2004) and The Departed (2006). His performance in the 2003 film The Cooler garnered him a nomination for the Academy Award for Best Supporting Actor.

Since 2006 he has starred as Jack Donaghy on the NBC sitcom 30 Rock, receiving critical acclaim for his performance and winning two Emmy Awards, four Golden Globe Awards, and seven Screen Actors Guild Awards for his work on the show, making him the male performer with most SAG Awards ever.
