Rees received a Tony, as well as an Olivier Award, for his performance in the title role in The Life And Adventures of Nicholas Nickleby. In addition, he received a Tony nomination for Indiscretions. Among his other Broadway credits are Uncle Vanya and The Rehearsal.
Rees may be best known from his portrayal of Robin Colcord on NBC's Cheers, where he worked with his upcoming Addams Family co-star, Bebe Neuwirth. The two subsequently collaborated on the Kurt Weill revue Here Lies Jenny and they also appeared opposite one another as Kate and Petruchio in The Taming of the Shrew at the Williamstown Theater Festival.
