What are the biggest mistakes you discovered with the Severus Snape dubbing voices and translations?

I don't like the dubbing in French. Not that the French actor dubbing Alan Rickman was not good - but it was just not 'him'. Alan's voice is so special, so unique, that I doubt it can be dubbed adequately. That's why I watch all his pelikula (not the HP pelikula only) in original version.

All the times Severus (well, Alan) opens his mouth to speak, it's perfection made sound. But there are two times when I get particularly... let's say... aroused :

- in the Great Hall scene, in the last movie, when Severus makes his speech about Harry being sighted in Hogsmeade. He ends it with "... now !" I must confess that every time I hear or read that word 'now', I can't help thinking about him !

- in the HBP, in the Spinner's End scene, when Severus tells Bella to "put it down, Bella, we mustn't touch what isn't ours'. I've always thought that Severus is a very possessive wizard. When I heard him say that (and the way he did of course), I gasped ! My dream come true ! I had to focus a lot to get back into the movie...

Well, these are my impressions over his voice. As a singer, I'm very sensitive to voices in general and his in particular is just so... well, you see what I mean. Alan is an exceptional actor because pretty much like a singer can, he can play with his voice to convey many feelings and/or emotions.
