Marc Bruni will direct the evening that will feature musical tributes, readings and clips from Plummer's lengthy career on stage. His colleagues will also offer tributes during the 6:30 PM event at the Edison Ballroom. O'Neill executive director Preston Whiteway and chairman Tom Viertel will host the evening.
Spacey (Richard III, "American Beauty") was honored with the Monte Cristo Award in 2009. He will present Plummer with the 2013 honor.
A two-time Tony Award winner for Cyrano and Barrymore, and beloved for the film of "The Sound of Music," Plummer is being honored for "his monumental achievements and contributions to the American and international theatre community."
"We are truly honored to present Christopher Plummer with the Monte Cristo Award. Mr. Plummer's unmistakable footprint upon stage and screen defines the Monte Cristo Award – artistic excellence and a lifelong commitment to theatre. His fondness for Eugene O'Neill's work and impact on the American stage is profound. I look forward to an incredible night in April," said O'Neill executive director Preston Whiteway in a statement.
Previous Monte Cristo recipients include Michael Douglas, James Earl Jones, Harold Prince, Neil Simon, Jason Robards, Jr., Edward Albee, August Wilson, Zoe Caldwell, Brian Dennehy, Karl Malden, Arthur & Barbara Gelb and Wendy Wasserstein.
