Three of the original Dagenham seamstresses invited Sally Hawkins for tea, prior to the filming, as they wished to inform her properly about mindset behind the strike, that she was set to portray in the film. Hawkins' grandmother also worked as a seamstress, although not at the Dagenham factory.
Sandie Shaw who sang the film's title song used to work as a punched-card operator in the Ford plant at Dagenham several years before the events depicted in the film.
The film was screened for the Dagenham women before it went on general release.
During the television premiere on 9th March 2013, the BBC experimented with the first ever Twitter-based director's commentary, whereby Nigel Cole and composer David Arnold live-tweeted along with the film.
