Anyone know of some awesome book trailers?

[Nick]

Hi all,
I'm looking in to book trailers at the moment and was wondering if anyone could point me in the direction of some truly great ones. I used to work in the film industry so I know a fair bit about constructing trailers for film and TV, but book trailers are a whole new concept for me.

How effective are book trailers at increasing attention for your books? I've seen a fair few and most, if I'm brutally honest, have left no impression on me but I'm unsure if that is because I'm too critical...

Any help/advice would be gratefully received.

Mine has generated lots of sales. It's really a simple one. I posted it on my FB Author page and did a $15 boost ad.
