For the film version of "Dad's Army" (1971), Liz Frazer was cast as Mrs Pike. This decision was made by the director, Norman Cohen, who wanted a less 'homely' actress for the role. The recasting was very controversial and one of the changes imposed by backers Columbia Pictures that added to the unhappiness of the cast. Co-writer of the television series, Jimmy Perry, has said "It was a mistake...not to cast Janet in the role because the viewing public has come to recognise her as Mrs. Pike. But that was a decision made by Columbia".
