Finally saw it! - The Cane and the Room.

Carol earlier:

> There was no mention of DD destroying [the ring] (it didn't appear to be broken, and, IIRC, we couldn't even see the stone), but the ring acted in some way that made Harry seem temporarily possessed. It clearly had *not* lost its powers, and DD didn't wear it to Slughorn's house as in the book. (I don't recall any distinction being made between its being a Horcrux and the curse that blackened DD's hand, either--and no indication that Snape's "timely action" had saved DD's life).
 
md responded:
> DD did infer that he destroyed the horcrux, that is, after all, how his hand got messed up and he doesn't imply to Harry that he received the wound destroying the horcrux.

Carol again:
I don't remember DD's implying that he'd destroyed the ring Horcrux. Can you refresh my memory? I also can't remember exactly how Harry reacted, only my impression (and that of the person I was with) that the ring sensed Harry's presence--or the soul bit in his scar--as it would not have done if it hadn't *still* been a Horcrux (in the film, that is).

I do remember his holding up the destroyed diary and saying that it had been a Horcrux (one down; six or seven to go). But I don't recall any indication that the ring Horcrux is destroyed, or any connection between it and the curse that blackened DD's hand.

As we know from the books, it wasn't the Horcrux but a curse on the ring (removed by Snape) that blackened DD's hand, and he put it on not because it was a Horcrux (which would have been stupid in the extreme) but because it was a Hallow, as we find out in DH (more reason why we need "the Prince's Tale"!). Obviously, the film can't reveal that information, but I don't think it even indicated that the stone in the ring was broken or that Snape played any part in saving DD from the curse. In fact, IIRC, the curse on the ring wasn't mentioned at all (and the blackened hand very underplayed).

Carol, for whom that part of the film is just a blur
