New Yorkers are being urged not to panic today as a Sherman tank rolls past barbed-wire fencing, sandbag walls, and army guys with guns stationed outside of the Brooklyn Museum. Apparently the terrifying makeshift battlefield is just a set for NBC's upcoming Kings, and Brooklynites should not expect any actual firefights (though traffic was closed on Eastern Parkway for a few hours). As you may recall, Kings was NBC's only new mid-season show that the network neglected to advertise during the Super Bowl, prompting worry that they might not know how to market it. So it's certainly nice to see that they've cleared that up. More scary wartime imagery, plus an apologetic flier, after the jump!
