Doctor Who alum Bonnie Langford is returning to the show to star alongside Ncuti Gatwa in the new series, the BBC and Disney+ announced today. Starting in 1986, Langford played the Time Lord's companion Melanie Bush opposite the versions of the Doctor portrayed by Colin Baker and Sylvester McCoy. She reprised the role last year for the final episode of Jodie Whittaker's tenure in the TARDIS.
