Bonnie Langford came to prominence in Britain as a child star in the 1970s, when she had a notable role in the TV series Just William. In the 1980s, she became familiar to Doctor Who fans as Melanie "Mel" Bush, the somewhat controversial TARDIS companion opposite Colin Baker and, later, Sylvester McCoy, during the program's 23rd and 24th seasons. She revived the character years later for Big Finish Productions' line of Doctor Who audios, breathing fresh life into the character... and universal acclaim for her performance. Ms. Langford has become well known for her appearances in many musicals in the West End and on Broadway, including shows such as Peter Pan, Cats, The Pirates of Penzance, 9 to 5 and Chicago. She portrayed the role of Carmel Kazemi on the BBC soap opera EastEnders from 2015-2018, for which she received the 2016 British Soap Award for Best Newcomer. She briefly appeared in the 2022 Jodie Whittaker finale "The Power of the Doctor".
