To Catch a Thief was a mid-20th century movie starring Cary Grant and Grace Kelly, involving cat burglars operating on the Riviera.
In an alternate timeline, when the USS Voyager was severely damaged by the Krenim in 2374, B'Elanna Torres did wrongly remember Clark Gable starring in the To Catch a Thief, when in fact it had been Cary Grant. Harry Kim believed, this mistake came from the identical initials of the two, C.G. (VOY: "Year of Hell")
To Catch a Thief was directed by Alfred Hitchcock in 1955.
