Movies aren’t plays, but it’s amazing how movie versions of plays, every once in a while, can make audiences momentarily forget that. A decade after seeing Dreamgirls, I can easily pinpoint the four moments in Jennifer Hudson’s “And I Am Telling You I’m Not Going” solo that caused our cheering crowd to burst into applause. Thirty-five years after the fact, I can still hear, with perfect clarity, the relieved laughter and ovation at On Golden Pond’s finale when Henry Fonda looked up at Katharine Hepburn and said, “I think I’m feeling all right now.” And if you ask me years down the road, I think I might also have instant recall of which revelations in the August Wilson adaptation Fences elicited loud, collective gasps at my screening, to say nothing of the Viola Davis line reading that, were this an actual play, might have stopped the show for a full 30 seconds.
