Except for Imelda Staunton, none of the actors knew that the film was about abortion until their characters find out. Each actors only knew what concerned their characters.
All actors were forbidden to even tell their family what they were doing, what the film was about during filming.
The budget was so tight that a week of filming had to be cancelled.
Filmed with no script, the film went on to be nominated for Best Original Screenplay for 2005 Oscar. Mike Leigh said that he "had to prepare the screenplay so it can be sent out to academy members. But actually the screenplay that was nominated doesn't exist. The film is the screenplay."
Mike Leigh asked the actors to hum in the movie. Because they couldn't afford to buy rights to songs, the actors had to hum something generic.
Submitted for the 2004 Cannes Film Festival but was denied.
