According to the director, Judi Dench was always slightly nervous that they would edit her speeches, as she had learned them. During the 'sherry-sipping' party before the opening of the theatre, at two points, Thelma Barlow's character prompts her in her speech ("Bread line... Employment"). This wasn't in the script, but Stephen Frears thought it was funny so included it into the final cut.
In the scene where Van Damm and Mrs Henderson were arguing about the name Millettes (or Millerettes), it is all done in one continuous shot. Stephen Frears thought it better to 'stand back and let the actors interact'.
