Who says Pointillism is dead? Georges Seurat’s “A Sunday on La Grande Jatte—1884” (1884–86) came to life yesterday at the Art Institute of Chicago, where figures from the well-known painting appeared at the top of the Grand Staircase leading to the Impressionist Galleries. Standing in front of a full-sized replica of the beloved canvas that had been stripped of many foreground characters (thanks to the digital manipulations of Michael Lande), the costumed ensemble broke into song: “Sunday,” from Stephen Sondheim and James Lapine’s Sunday in the Park with George. The painterly flash mob—alas, sans monkey—was out to promote Chicago Shakespeare Theater’s upcoming production of the the Tony- and Pulitzer Prize-winning musical, which opens September 26 under the direction of Gary Griffin, and features Jason Danieley as George and Carmen Cusack as Dot/Marie.
