The Sealyham surged in popularity after the First World War in the UK and the United States. Within the Hollywood film industry, the Sealyham became a fashionable dog to own by the Hollywood elite. The terrier was owned by actors Tallulah Bankhead, Humphrey Bogart, Bette Davis, Elizabeth Taylor, and by writer Agatha Christie. Cary Grant owned one which he named Archie Leach – Grant's real name. Alfred Hitchcock had one of his Sealyham Terriers seen in his 1941 film "Suspicion". Alfred Hitchcock can also be seen at the start of his 1963 film, "The Birds", walking two of his Sealyham Terriers in a cameo appearance, although he also owned a third Sealyham not featured in the movie. The British Royal Family also favoured these dogs; King George V owned a dog named Jack. In 1959 one Sunday newspaper reported in the UK: "A notice has been posted in Clarence House and Windsor Castle giving explicit instructions that when Princess Margaret has breakfast in bed, her two Sealyhams must be brought to the room along with her breakfast tray." These two dogs were called Pippin and Johnny, and were looked after by the Queen Mother when Princess Margaret fell ill. In the 1960s, children's author Maurice Sendak owned a Sealyham named Jennie, which he featured in his 1967 work "Higglety Pigglety Pop!".
