Question: Of the characters who married in 1986, which of their actors was younger? Passage:Linda was introduced as the wife of Mick Carter, played by Danny Dyer, the brother of established character Shirley Carter (Linda Henry), who has appeared in EastEnders since 2006. Luisa Bradshaw-White joined the cast as Shirley's sister Tina Carter in early November, and Linda was the second new Carter to appear after her. Kellie Bright's casting was announced alongside Danny Dyer's on 1 October 2013, a week after Bradshaw-White's casting was revealed. Linda was described as having been with Mick since they were teenagers, and despite not being 'blessed with brains', is a 'tough woman who will always fight tooth and nail for her family - especially her children'. Bright previously appeared as a bridesmaid in 1986 at the wedding of Michelle Fowler (Susan Tully) and Lofty Holloway (Tom Watt), and starred in scenes opposite her current co-star Letitia Dean, who continues to appear as Sharon Watts. Bright estimated herself to be aged 10 at the time. She also auditioned for the role of Tanya Branning in 2006, a role that was eventually given to Jo Joyner.
