Malcolm-Jamal Warner, of “The Cosby Show” and “Community,” will star in the Huntington Theatre Company’s production of “Guess Who’s Coming to Dinner” from Sept. 5-Oct. 5. David Esbjornson, who helmed the Huntington’s production of “All My Sons” in 2010, is directing Todd Kreidler’s take on the 1967 film, which was written by William Rose. Warner (inset) has already starred as Dr. Prentice (played by Sidney Poitier in the film) under Esbjornson’s direction. He played the part at Arena Stage in Washington last winter. The Huntington says Kreidler’s script has evolved since the D.C. run and that the local production will be different — and will have a new cast.
