That Darn Cat! is a 1965 American thriller comedy film directed by Robert Stevenson and starring Hayley Mills and Dean Jones in a story about bank robbers, a kidnapping and a mischievous cat; produced by Walt Disney Productions. The film was based on the 1963 novel Undercover Cat by Gordon and Mildred Gordon. The title song was written by the Sherman Brothers and sung by Bobby Darin. The 1997 remake includes a cameo appearance by Dean Jones. That Darn Cat! was both Hayley Mills' last film of the six she appeared in for the Walt Disney Studios, and Dean Jones' first film for Disney. Mills later said it was a mistake to leave Disney. Plot "Darn Cat" or "DC" is a wily, adventurous Siamese tomcat who lives with young suburbanite sisters Ingrid "Inky" and Patricia "Patti" Randall and enjoys an evening route wandering thru town which includes teasing local dogs, swiping food, and marking vehicles with muddy paws. One night, DC follows bank robber Iggy into an apartment where he and his partner Dan are holding bank employee Miss Margaret Miller hostage. Miss Miller uses the opportunity to replace his collar with her watch, on which she has inscribed most of the word "HELP," and releases him to go home to the Randalls. Patti discovers the watch on DC and suspects that it belongs to the kidnapped woman. She goes to the FBI and tells Agent Zeke Kelso of her discovery, and Supervisor Newton assigns Kelso to follow DC in the hope that he will lead them back to the robbers' hideout. Kelso sets up a headquarters in the Randalls' house and assigns a team to keep the cat under surveillance, but, despite multiple attempts and a bugging system, DC eludes them in humiliating and comedic ways, culminating in a chase where he leads Agent Kelso through several back yards and a drive-in theatre. As DC ends up trying to open a pigeon cage and is discovered by the owner Gregory Benson, who is in Ingrid's carpool, chases DC and Kelso and, out of frustration, tells Ingrid he is leaving her carpool. The next day agent Kelso's supervisor Newton shuts down the operation, considering the evidence of the watch not hard enough, but Patti disguises herself as the hippie niece of her friend Mr. Hoffsteddar the jeweler and persuades the FBI that the watch was indeed hard evidence.
