(covers information from an alternate timeline)
There was a holographic version of the movie, which B'Elanna Torres had seen twice.
In an alternate timeline, when the USS Voyager was severely damaged by the Krenim in 2374, B'Elanna Torres wrongly remembered Clark Gable starring in 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")
