Nearest and Dearest is a 1972 British comedy film starring Hylda Baker and Jimmy Jewel as feuding brother and sister Nellie and Eli Pledge, owners of Pledges Purer Pickles. A spinoff from the long running TV sitcom of the same name, it was produced by Hammer Films in conjunction with a film making arm of Granada TV. As well as starring in the film, Hylda Baker also sings the title theme song. Despite the popularity of the TV series, the film version failed to match that success at the box office.
Sky Movies said, a kind of bumper bundle of seaside postcard jokes, with acting honours going to Jimmy Jewel, underrated as a character actor, and Yootha Joyce, who pops up as Mrs Rowbottom.
