Fairy tales seem to get related to everything these days/weeks (and with no additional help from me!). In Cymbeline they wouldn't be stretching the idea too far, of course, but I'm curious to see just which ones they cite as having parallels. If Snow White doesn't come up you can then assume fairy tales are just the current hot-button-scapegoat for unveiling the darkness in us all... (insert ridiculous evil laugh here). But hey - at least they're open to discussing our favorite subject!
If you're interested in Shakespeare, seeing his work translated into modern or are curious about the Snow White motifs in the play (which will have to be there in the movie to some extent since they're following the book so closely) then you might want to keep your eye on this film too.
Take a look at the trailer. It looks better than the poster implies and we might even be getting a glimpse of Imogen's death-like sleep. Or is it sleep-like death? Depends on the story you're telling I suppose... :
