Watch Constellations' Jake Gyllenhaal Get Wet & Talk His & Big Sister Maggie's Broadway Debuts

Jake Gyllenhaal, who will soon make his Broadway debut in Constellations, stopped by The Tonight Show on October 29 and revealed that he’s one proud little brother. The Oscar nominee’s sister Maggie is also appearing on the Great White Way for the first time this season in The Real Thing, which officially opens tonight, and although “she didn’t want me to see her at first,” he caught a preview and thought she was “pretty extraordinary.” Gyllenhaal went on to talk about his upcoming movie Nightcrawler, before getting wet with host Jimmy Fallon. Check the videos out below, then see Maggie in person at the American Airlines Theatre and (a presumably dry) Jake, from December 16, at the Samuel J. Friedman Theatre.
