Midday theater critic J. Wynn Rousuck joins us on this Wednesday afternoon (we're broadcasting live on Thursday from the Enoch Pratt Free Library) for another of her weekly reviews of the Maryland stage. Today, she spotlights the new production of Proof that opens the 2019-2020 season at Baltimore's Everyman Theatre.In playwright David Auburn's Pulitzer Prize- and Tony Award-winning play, which opened on Broadway in October 2000, we meet Catherine, who has inherited her late father Robert’s house, hundreds of his notebooks, his mathematical genius, and, she fears, his debilitating psychoses. She grants one of her father's best students, Hal, permission to comb through his voluminous writings, where he discovers a revolutionary mathematical proof -- a discovery that sparks a crisis of identity for Catherine. Everyman Resident Company member Megan Anderson, who played Catherine in Everyman's sell-out first production of Proof in 2004, returns to play Catherine’s older sister, Claire. Joining Ms. Anderson in the cast are Jeremy Keith Hunter as Hal, and fellow resident company actors Katie Kleiger as Catherine, and Bruce Randolph Nelson as Robert. Proof, directed by Resident Company member Paige Hernandez, continues at Everyman Theatre through October 6. Follow the link for showtimes and ticketing information.
