Dustin Hoffman planned the moment when he throws his wine glass against the wall during the restaurant scene with Meryl Streep. The only person he warned in advance was the cameraman, to make sure that it got in the shot. Streep’s shocked reaction is real, but she stayed in character long enough for the director to yell cut. In the documentary on the DVD, she recalls yelling at Hoffman as soon as the shot was over for scaring her so badly.
