Dame Sybil Thorndike, Kathleen Harrison and Estelle Winwood, collectively representing some 200 years of British theatrical history, are top-billed in this feathery bit of whimsy. The starring trio plays three elderly residents of a nursing home, fed up with their monotonous existence. They engineer an escape from their drab surroundings and head for an impromptu holiday on an Irish island. Stanley Holloway plays a likeable old codger who becomes the ladies' partner in "crime." Alive and Kicking refuses to patronize its leading characters--or the mature audience to whom this charming comedy is aimed.
