I am french so it's not easy to awnser you but I think comedies like "la tour montparnasse infernale" or "l'auberge espagnole" (A very good film especially for languages learners), "la cité de la peur". And a last one kind of weird " la fabuleux destin d'amelie poulain".

Karaoke is a funny method for catch the sounds with typical songs : http://www.youtube.com/watch?v=h5G49m184LU&feature=related Otherwise, for the films, I recommend you all subtitled films or Blockbuster films like the serie such "Taxis", which I put you an extract just below : http://www.youtube.com/watch?v=ZvJjJMQrcHI But sometimes the used French is a little familiar. You'd just to find some subtitles.

Mylene Farmer`s songs and lyrics for them. See google etc.

I think that "la chanson du dimanche" could be great to hear French cause elocotion is good. We don't know what kind of music you like so it's not easy.
