A charming adaptation of British zoologist Gerald Durrell's recollections of his years as a teen (played by Eugene Simon), spent with his offbeat mother (Imelda Staunton) and siblings on the Greek island of Corfu before World War II, amid odd creatures: crawling, flying and human. Larry: Matthew Goode. Leslie: Russell Tovey. Margo: Tamzin Merchant. Spiro: Omid Djalili.
