Nero Wolfe is a television series adapted from Rex Stout's series of detective stories that aired for two seasons (2001–2002) on A&E. Set in New York City sometime in the 1940s–1950s, the stylized period drama stars Maury Chaykin as Nero Wolfe and Timothy Hutton as Archie Goodwin. A distinguishing feature of the series is its use of a repertory cast to play non-recurring roles. Nero Wolfe was one of the Top 10 Basic Cable Dramas for 2002.
