Yeah we gots it already... and why? because while DD died a death in the USA on release We Brits ate it up, made it a huge success and kept it alive till you guys realised what you had missed. Therfore we get the DVD before you because we deserve it.
I meant to post a fuller review of DD : DC once I'd digested - so now seems like as good a time. The differences in the DC version of DD are sometimes quite subtle. The first and most obvious one (to me) was that Echo & The Bunnymen playing The Killing Moon at the very beginning of the film (Donnies bike ride home) has been replaced with INXS. It's not a bad change, just jarring…
From then on the changes are far more subtle. Some scenes are extended ever so slightly and allowed to play out. Donnie has a lot more interaction with his family and therapist fr instance. This doesn't mean "more donnie" this actually allows the supporting cast to step up and take a moment: as a result the "world" around donnie seems more real and more convincing. Plus it's such a great cast it's never a dull moment when they are giving up the acting goods.
Lots more in the way of exposition of the tangent universe idea and the sci-fi-ness of the plot: those of you who read the excerpts from Grandma deaths book The Philosophy Of Time Travel on the Donnie D website will recognise a lot of the onscreen text.
What else..? Some of the effects seem to have been jazzed up and you can find lots more in the way of "random" synchronicity in the story and visuals that give DD it's dreamlike "everything is connected" quality. A huge thumbs up: The DC is the definitive Donnie D in my house.
