Life is a Cabaret - or, at least, the March 8 Ten Unknowns opening night party was one. Former revival cast members John Benjamin Hickey (who played Clifford), Jennifer Jason Leigh (former Sally Bowles) and Denis O'Hare (who played Ernst) attended the Jon Robin Baitz play's opening, in which O'Hare plays an art dealer. In Ten Unknowns, Donald Sutherland — sporting a mane of white hair and a beard — plays Malcolm, a once promising painter who once haunted post-war New York. He now lives in Mexico, where he fled three decades before to escape the hegemony of the Abstract Expressionists (Malcolm is a figurative artist). But with the help of slacker art student Kirk, Malcolm has mysteriously begun producing some of the best paintings of his career, causing dealer O'Hare to see dollars in a Manhattan retrospective of the old man's work.
