I don't think they're available in English, but they do have subtitles available. That said, if they are available somewhere in English I don't think it would do the movies justice. The French is beautiful if you understand it.
I'd like to check them out too. My wife and I used to watch a lot of "international" films but haven't in the last couple of years. Honestly, I think we are just so damned tired by the time we watch a film that we don't feel like reading. But I'll throw those two on the "watch list" we have. Your choice of Back to the Future threw me for a loop. Don't get me wrong, I love that movie and it definitely takes me back to being a kid but top 5? I just heard Michael J Fox on Stern recently, what a fella. I really dig that guy. -You have a diverse list my friend.
