Hilda Ogden
Alexander quit the role of Hilda in 1987 after 23 years but was persuaded to reprise the part in 1990 for a one-off appearance as part of an ITV Telethon. She has also been seen in a spin-off video in 1998, in which another long-running character, Betty Williams (Betty Driver), visited her at her new home. Both of these appearances are considered canon to the show.
