A production of playwright Tom Stoppard’s first hit, the tragicomedy Rosencrantz and Guildenstern are Dead, has entertained audiences at the Folger for the past several months. But while Stoppard’s comedies induce chortles among theatergoers, his latest play asks audiences and characters to deal with more serious, scientific concerns. The Hard Problem, broadcast at Sidney Harman Hall as part of London’s National Theatre Live series, follows Hilary, a young psychology researcher who has a hard time figuring out where her field intersects with biology and how these issues intersect with idea of consciousness. Meanwhile, Hilary finds herself in a personal crisis that places her at odds with her colleagues and has her looking to religion for answers. The struggle to meld all these different belief systems leaves the characters and the audience questioning their own beliefs and acceptance of things just the way they are. Stoppard, a formidable thinker, wouldn’t have it any other way. The broadcast begins at 7:30 p.m. at Sidney Harman Hall, 610 F St. NW. $20. (202) 547-1122. shakespearetheatre.org.
