Enter, sand man!
It is little plastic shovels at 10 paces! The Coney Island Sand Sculpting Contest is back on the beach for its 24th year. Come cheer on the artists and amateurs building amazing coastal creations, and help raise money so people affected by Hurricane Sandy can do some building and rebuilding of their own.
Noon at Coney Island Boardwalk [Boardwalk at W. 10th Street in Coney Island, (718) 266–4653, www.facebook.com/coneyislandsandsculpting]. Free.
Talk about jazz hands — Arturo O’Farrill, founder of the Grammy-winning Afro Latin Jazz Orchestra, will tinkle the ivories and get Brooklyn Bridge Park grooving to Cuban rhythms with a free concert at Harbor View Lawn. Bring a picnic blanket and bring it early to make sure you secure a space.
7 pm at Brooklyn Bridge Park Pier 1 (Old Fulton Street at Furman Street in Dumbo, www.brooklynbridgepark.org). Free.
You’ve seen “Dog Day Afternoon,” now see “The Dog,” a new documentary that tells the real story of John Wojtowicz, whose abortive stick-up at a Gravesend bank inspired the Al Pacino flick. Nitehawk appears to be the only place in Brooklyn screening the movie — and it would just feel wrong to see it anywhere else.
5:10 pm at Nitehawk Cinema [136 Metropolitan Ave. near Berry Street in Williamsburg, (718) 384–3980, www.nitehawkcinema.com]. $11.
The Brooklyn Comedy Festival takes place at many venues around the borough Aug. 18–24, but this is our pick. “Impro(vs)tandup” brings improv artists and stand-up comedians together to do their thing — and then each other’s things. Performers will include “Saturday Night Live” star Sasheer Zamata and the US National Improv Team.
8 pm at Glasslands (289 Kent Ave. between S. First and S. Second streets, www.bkcomedyfestival.com). $8.
