Real-life rugby players Harriet and Bridget Millar-Mills are also sisters, who grew up learning to play the sport together.
Guinness tells the story of the duo in its ad for the Women’s Six Nations Championship. Harriet and Bridget ended up playing for opposing England and Scotland national teams, going head-to-head in the 2013 Women’s Six Nations. They are rivals on the pitch but always sisters beyond. The work was created by Tim Riley and directed by Tubby Brother through Tubby Brother Films.
