I'll be honest here. I'm a big fan of Tim Burton, and I have most of his movies on DVD. That said, I hate his policy of filming American stories overseas with foreign actors that he started with Sleepy Hollow; there were at least a dozen major and supporting characters in that film, and if I remember correctly, only three were actually played by Americans (Depp as Crane, Christina Ricci as Katrina, and someone else I can't remember at the moment). Granted, this is Dark Shadows, where Quentin from New England speaks with a West Virginia accent, but it annoys me all the same. Also, though I love Burton's brand of dark comedy, I simply don't want that applied to Dark Shadows, at least not in huge amounts. If he films it here with a pinch of his trademark humor, local actors, and a lot of visual flair, I'll be pleased. If he uses a nearly all-British cast and/or overdoes the humor, I'll be disappointed.
However, one Brit I definitely wouldn't mind seeing involved (and if Burton is the director, it's a sure thing) is Helena Bonham Carter. Did anyone else think "Barnabas and Julia" during the wedding bit in Sweeney Todd?
