maybe via identification of the car we can find if it is on the site?

When looking at an available list of movies said to have been made by Pathé-Natan (I didn't find a list of the movies made in their studios), it seems that only 2 movies from 1933 to 1935 are present for now in the IMCDb:
Le bonheur, 1934;
Justin de Marseille, 1935.

Guy Loos says a Panhard & Levassor from late 1933 or 1934, but I don't think the concerned convertible is in any of these movies, even with another identification. And as it could be a special body made by a coachbuilder, it could be hard to find the accurate model if it is present in another movie.
Unless some Chapron's, Saoutchick's or Pourtout's berserker wanders the neighborhood

The convertible in Guy Loos' picture is a P&L without any doubt, when looking at the details. See here (fr) the 1934+ car line with the Panoramique body.

If I'm not mistaken, the closest model found in the IMCDb is this 1936 Panhard & Levassor 6 CS Victoria in César. But it's a 1936 model in a 1936 movie shot in Marseille by Les Films Marcel Pagnol (fr)

Hello

I think the film, although made in 1934 or 1935, could have been finished only in 1936. It could also be that this scene was not used in the movie ....

Hello

I found another picture of this car, it is the same car in the same movie, without any doubt. Could someone perhaps identify the movie now?

Thanks

4043-RG4 was a 1933 Paris plate according to a table in http://plaque.free.fr/f_rec3e.html

The movie is Tout pour rien directed by René Pujol (1933).
We see Françoise Rosay in the rumble-seat, a real mother-in-law seat according to the story.

Et voilà. Tout vient à point à qui sait attendre.

Tiens, de la visite rare.. avoir su, on aurait fait un peu de ménage...

Bon retour Didier

Il me semble qu'on avait parlé de cette voiture (on ignorait encore dans quel film) avec une autre photo (une photo de tournage, on voyait la voiture avec un caméraman et les projos et tout) mais dans quel sujet ? (Je le dis car il me semble que j'avais donné quelques ébauches de réponses que je ne vois plus ici.)

... A y est, c'était ici, https://imcdb.opencommunity.be/forum_topic-8100-80093-Panhard_cabriolet_model_1933___1934.html#p80093.

Notons que c'est un film de 1933 (sorti en salles en septembre 1933).
