To Catch A Thief (1955)

Based on the 1952 novel by David Dodge (1910-1974) 

Directed by Alfred Hitchcock 

Screenplay by John Michael Hayes

Cary Grant (1904-1986) stars as a retired cat burglar who has to save his reformed reputation by catching a new burglar preying on the wealthy tourists of the French Riviera. Grace Kelly (1929-1982) stars opposite him as his romantic interest in her final film with Hitchcock. Robie's plan is to prove his innocence by catching the new cat burglar in the act, so he enlists the aid of an insurance man H. H. Hughson (played by John Williams). He is an Englishman who reluctantly obtains a list of the most expensive jewels currently on the Riviera. The first owners listed are Jessie Stevens (played by Jessie Royce Landis) and her daughter Frances (played by Grace Kelly). So Robie strikes up an acquaintance with them.
