Early Life

Because he shares his birth name with another actor, Leonard uses the name of his brother Sean for his Screen Actors Guild membership.

Leonard is a three-time Tony Award nominee (1993, 2001 and 2003), winning in 2001 (Best Actor – Featured Play) for his role as A. E. Housman in Tom Stoppard's The Invention of Love. He had a prior association with Stoppard's work, playing the role of Valentine in the New York premiere of Arcadia at Lincoln Center in 1995.

In 1997 Leonard received rave reviews for his role in the Christopher Reeve-directed television film, In the Gloaming. Entertainment Weekly said that, in the film, Leonard "does a first-rate job of juggling Danny's mixture of despair, neediness, and mordant jokiness."

From 2004 he played Dr. James Wilson, head of the oncology department, on the FOX TV series House, M.D., until the series ended in 2012. In 2007 Leonard appeared on Entertainment's Weekly's 100 list as "Dr. Underrated".
