Here's a really impressive trailer for a film that was completely off my radar, Daybreakers. Stars Ethan Hawke and Willem Dafoe, and set in a world in which Vampires are the majority and humans the hunted underclass. Pushes all my buttons, really.
The surprisingly good, even mature looking (I know, I know), trailer for Torchwood's Children of Earth mini-series (running in five parts Mon to Fri in a single week.)
I'm intrigued by the Johnny Depp / Christian Bale / Michael Mann gangster flick Public Enemies, even if the trailer is just an abridged version of the entire film as far as I can tell. Although he can be quirky and mannered as an actor, Depp is such a chameleon sometimes.
And BIG 'SPLODY THINGS. Roland Emmerich destroying the world again in 2012. Unlike Transformers, the astonishing spectacle of this one may actually lure me to the cinema against my better judgement.
Finally, and on a slight tangent, I'm a complete nerd sometimes but this CGI image from a forthcoming Trek calendar is just stunningly beautiful. In a nerdy way. (From the blog of Doug Drexler, an FX guy from Trek / BSG.)
