From Wikipedia: It was also performed by Steve Martin and Bernadette Peters in the 1979 movie The Jerk. Jazz ukulele player Lyle Ritz actually played the ukulele accompaniment for the scene. On the 26th Anniversary DVD re-release there is a tutorial by Ukulele Gal on how to play "Tonight You Belong to Me" on the ukulele.
That is indeed very true. Though Steve M can play the uke, yet prefers the banjo on which he is highly accomplished. Another interesting Jerk fact. Watch this scene and when they get up an leave you hear a crack. It was Steve Martin mistakenly treading on the uke he was using.
Don't forget MADONNA!
