Bed-Stuy got a taste of Hollywood Monday night when “The Hurt Locker” star Anthony Mackie threw open the doors to his new old-timey watering hole, NoBar on Nostrand Avenue. Samuel L. Jackson and Sam Rockwell dropped in and mingled with locals around a red-felt pool table. And Mackie played barman with two colleagues in long-sleeve waffle shirts and suspenders beneath paintings by Justin Bua and two flat-screen monitors. The actor’s Los Angeles-based manager — as in talent, not restaurant — Jason Spire even got into the act, playing triple duty by schmoozing, overseeing a photographer and passing out red beans and rice. “I wanted to watch a game one night, and I found out the only place around to see it was Applebee’s,” Mackie quipped regarding his choice of location. He said he’s hoping Nets fans will “come and chill” once the nearby Barclays Center opens.
