Melvyn Hayes

Melvyn Hayes played Wilkin in the webcast version of Shada, as well as its audio release, and the Scorchies in the Big Finish Doctor Who audio story The Scorchies, which also saw him voice Jon Pertwee's Third Doctor during a body swapping experience.

Wilkin was played in the original television version of Shada by Gerald Campion. When recasting the late Campion's role for the audio/webcast version director Nicholas Pegg remembered that Hayes had appeared alongside Campion in the television series, upon which casting Hayes as Wilkin became "irresistible."

Hayes is the former husband of Wendy Padbury and the father of Charlie Hayes.
