I'm not a fan of teaser trailers that come out a year before the movie does. (I'm a fan of the book, so I'm going to see this movie, teaser or no teaser.) I don't think filming has even started on this movie, so they can't show actual scenes. I'd rather they get enough footage in the can to cut together a trailer that can actually show what the film will look like, even if they have to wait until "only" six months before the premiere.
I would love to see them make a movie version of Dan Brown's other book, Angels and Demons, though.
"Oh, now there's a surprise! I could have a heart attack and die from not surprised!"
Actually, filming has begun, but there is zero footage in the teaser. Then again, that's why they call it a teaser. It's just to get the buzz going and make people aware of the film's existence. it's all part of the marketing.
