If you tried to grab a cuppa at Oslo this morning, you were probably turned away and forced to trudge to one of the 5,000 other coffee spots on the avenue. The roaster’s Bedford Ave. location closed around 4:30 p.m. so that Morgan Freeman’s forthcoming dramedy, Life Itself, could shoot there. Oslo employees were incorporated into the shot, giving the celebrity barista at Grumpy a run for her money. One of them told B+B that the scene consisted of Freeman grabbing a cup of coffee — so, nothing exciting. But the movie — which also stars Diane Keaton and Cynthia Nixon and “centers on a married couple who get swept into a real estate bidding war when they put their Manhattan apartment on the market,” according to TheWrap — will be back in the neighborhood tomorrow and the next day.
