I think this might take the cake for my favourite trailer of the year. Any time the editing matches the music in a video clip I'm pretty much guaranteed to love it; add to that the stunning cinematography, lighting and costume in this trailer and I cannot wait to check out A Serious Man, even though I know almost nothing about the film (and I plan on keeping it that way so I get the most out of my viewing experience).
Oh, on a side note, the one thing I do know about the movie is that Colin Firth's character in the film is gay, although you wouldn't know it from the trailer. Seems like an interesting thing to omit; I'm sure you can come up with your own theory as to why.
A Single Man will be in theatres in the US from December 11th, and is currently schedueled for a release in Australia at some point in February 2010
