Literary adaptations seem to be most popular lately, in particular, Young Adult. With The Host coming out, The Mortal Instruments and Warm Bodies just to name a few, I can say I am in every way excited!
Another thing I have particularly noticed is the use of popular music on these such trailers. Beautiful Creatures use the wonderful Florence and the Machine 'Seven Devils', one of my favourite songs off of her latest albums to create the moody atmosphere that accompanies the book about Witchcraft in a small southern town. This is most probably a ploy to draw in a wider audience to their film and entice their current audience by showing they're 'with the times'. But what I love is the popularity it is giving bands. Every time that advert is played, the song plays with it and people here the tune and hum along, listen to the lyrics and decide they like the sound of it, google it, buy the album. And music that deserves to be heard, is.
What I also love is how many smaller scale bands are being thrust deservedly into the lime light :) Bands like The Black Keys are being featured on the Warm Bodies trailer and though they are veritably well known for their wonderful, dark music, having been featured on the radio and accumulating their own following, they are now featured everywhere, with a whole new audience listening to them who may have never discovered them before.

Like Jaws, I think if you took away the music from trailers, it would be boring and uninteresting. Music creates an atmosphere, sets a scene, terrifies you and even turns you to blubbering mess. To prove my point, if a soundtrack weren't included in a movie, would we ever have had musicals?
