Christopher Dormer appeared as Peter Barlow, son of Ken and Valerie Barlow, on Coronation Street from 1970 to 1971. He took over the role from Robert Heanue before it was recast again with Mark Duncan taking over later in 1971.

Emigrating to Canada with his parents in 1971, in March 1981, he was pictured in the TV Times magazine, aged 17, having a reunion with William Roache on a visit to Britain.
