A Little Romance (1979)

Synopsis
The disarming comedy A Little Romance features Diane Lane as a 13-year-old American, living in Paris with her businessman stepfather (Arthur Hill) and her promiscuous mother (Sally Kellerman). Mom is currently enamored with pretentious-filmmaker David Dukes, and it is on the set of Dukes' latest picture that Lane meets another 13-year-old, insatiable French film buff Thelonious Bernard. A likeable street-smart petty thief and gambler, Bernard is instantly attracted to Lane. With the help of roguish old Laurence Olivier, Lane and Bernard arrange a romantic rendezvous under the Bridge of Sighs in Venice. Naturally, when the kids disappear it's a cause for international concern, but all ends as it should. Some of the best moments in A Little Romance belong to Broderick Crawford, unselfconsciously playing "himself" at a movie party. ~ Hal Erickson, All Movie Guide
