First ":the movie"

What was the first movie subtitled with “:the movie.” I searched intenet movie database and the earliest reference I could find was Spin and Marty: The Movie from 1955. It seems to make most sense when making a cinema version of a TV show so there probably aren’t any before the WWII but is S&MtM the earliest one?

I’m surprised it was first used that early. I checked on the 1954 movie of Dragnet, which was an earlier adaptation to film of a populat TV show, and according t the IMDB it didn’t have the subtitle “The Movie”, it was just “Draghnet” until a later incarnation of the TV show, at which time it became “The Original Dragnet”.
