Hey guys,
I too was in search of a hat similar to this one. At first I thought it was a trilby, much like the felt version bond wears in the first few films, but then noticed that it doesn't have a factory pinch. I'm pretty sure this is simply a Porkpie with a stingy brim and a "tear drop" C dent.
I just purchased this hat as I think it's very very close. All it needs is a little pinch in the front and to be worn slightly crooked to achieve the screen look. (and a new ribbon if you really wanted it to be identical).

I'll post pics when I get it to compare to the screen shots.
Cheers!
