Argh, Le Monde's TV guide says that The River King was shown on Canal+ at 8.50pm...three days ago (Tuesday 28th). Sorry about the late notice. Bad blogger. Must check Factiva more often. Did anyone tape it perchance? Anyway, if you missed it, there are heaps of DVDs on eBay. The Canadian version has French audio.
Though if you're reading this, you can probably understand English.
