All the dialogue in the film is sung.
In the beginning, a black car rolls into the garage where Guy works, and Guy is asked to assist with the car's problems. This car is actually Roland Cassard's and it can be seen two more times: when Roland visits the umbrella shop to give Ms. Emery the money for her pearl necklace, and again as the wedding car. The license plate is the same and can be seen in this latter scene and in the very first.
Roland tells Genevieve's mother he once loved a woman named "Lola." "Lola" is a Demy film from 1961, in which Marc Michel plays the same character of Roland.
