The Atlantic Theater Company has been one of Off-Broadway's most successful theatre companies over the past twenty years, having won twelve Tony Awards, eight Lucille Lortel Awards, thirteen Obie Awards, and three Outer Critics Circle Awards. The company, originally founded in 1983 by the playwright David Mamet and the actor William H. Macy, has mounted over one hundred plays, many by new writers. Included among its successes are Martin McDonagh's The Lieutenant of Inishmore and The Beauty Queen of Leenane, Woody Allen's A Second Hand Memory and Writer's Block, the revival of David Mamet's American Buffalo, Celebration and The Room by Harold Pinter, Mojo and Night Heron by Jez Butterworth, and the new musical adaptation of Frank Wedekind's play Spring Awakening, which won the 2007 Tony for best new musical. But producing plays is only part of Atlantic's mission: it also runs the Atlantic Acting School, which operates both as a private conservatoire and an undergraduate training studio in conjunction with New York University. Its curriculum focuses on Practical Aesthetics, the acting technique developed by Mamet and Macy. Mary McCann, in conversation here with NTQ Contributing Editor Ian Watson, is a founding member of the Atlantic Theater Company and Director of the Atlantic Acting School, where she also teaches. She continues to act, having appeared in many of the company's productions, on Broadway, on television, and in several independent films. The conversation took place over two meetings at the Atlantic Acting School in New York City, on 25 April and 5 June 2007.
