Available Exclusively at Blockbuster on DVD
Tonight, I visited a nearby Blockbuster (in Larchmont, NY).
I stumbled over "Roman de Gare" in the new release section. The box said that it's being carried by Blockbuster exclusively. See http://www.blockbuster.com/catalog/movieDetails/431602
To my knowledge, there's been no announcement of a release date.
Anyway, I'm glad it's finally out, and that I can finally see it.
