There's a moment in "Birdman" where actor Riggan Thomson (Michael Keaton), performing a preview of his new Broadway play, is desperate for fresh air. Wearing only a bathrobe, he steps through a side exit of Manhattan's St. James Theatre, shuts the door on his robe and discovers he's locked out. Riggan then makes a mad dash through Times Square, leaving the robe behind. A horde of onlookers whip out their phones to shoot viral-ready footage of his underwear-clad blunder, Riggan's folly illuminated by rows of blinding electronic billboards. The camera trails him as he wraps around to the front of the theater and re-enters through the back of the house just in time for his cue.
Keaton didn't make it through Times Square without hearing the word "cut," but we wouldn't know that. In fact, all of "Birdman" employs this continuous-action technique. Try to count the number of cuts found in the movie's two-hour running time. You probably won't need one hand.
