BIO
After graduation, Martin toured the states with John Houseman's The Acting Company. He appeared in Shakespeare's Rock-in-Roles at the Actors Theatre of Louisville and The Butcher's Daughter at the Cleveland Play House, and returned to Manhattan to perform in local theatre, soap operas, and commercials. Finding that auditions, regional theater, and bit parts were no way to support himself, Martin waited tables at several restaurants around the city. He was serving a pizza when his appearance on CBS's Guiding Light aired in the same eatery. While the show aired, the whole waitstaff gathered around the bar television to cheer his performance.
Martin made his Broadway debut in Timon of Athens, and then performed in The Government Inspector with Lainie Kazan. While employed at the Moondance Diner, he met the playwright Jonathan Larson, who also worked on the restaurant's staff. In 1996, Larson's musical Rent took the theatre world by storm, with Martin in the role of gay computer geek/philosophy professor Tom Collins. The 1990s update of Puccini's La Bohème earned six Drama Desk Awards, five Obie Awards, four Tony Awards, and the Pulitzer Prize. In 1998, the West End production of Rent opened with four of the original cast members, including Martin. He played Tad in the concept album of Bright Lights, Big City.
In 2010, Martin returned to the stage for one of his biggest theater commitments since Law & Order, performing in the productions of The Merchant of Venice and The Winter's Tale as a part of The Public Theater's Shakespeare in the Park at the Delacorte Theater in Central Park. He played the roles of Gratiano and King Polixenes, respectively. The two shows were performed in repertory, beginning with previews on June 9, 2010, through to the final performance on August 1, 2010.
The Merchant of Venice later transferred to Broadway to the Broadhurst Theater for a limited engagement, in which Martin reprised his role as Gratiano. The show began previews on October 19, 2010, and officially opened on November 7. The show began a hiatus on January 9 to accommodate Al Pacino's pre-existing obligations, and resumed from February 1, 2011, to February 20, 2011; Martin did not reprise his role after the hiatus due to other work commitments. He took part in a one-night-only reading benefit of Romeo and Juliet to celebrate the 50th anniversary of the opening of the Delacorte Theater in Central Park, alongside Meryl Streep, Kevin Kline, Raúl Esparza, and others on June 18, 2012.
