Thelma Barlow – 92

Thelma Barlow is a British actress who made a name for herself on the long-time soap Coronation Street. She played Mavis Wilton, who was actually just supposed to be a cameo appearance. But Barlow portrayed the character so well that the viewers demanded the character back.

She would play the role from 1971 to 1997, followed by another starring role in the short but well-received sitcom, Dinnerladies. She played Dolly Bellfield, a socialite who always made snide remarks about others. She featured in a group of Dinnerladies video shorts in 2018 and also had a part in a 2019 Coronation Street Christmas special.
