we don't know. David Slade doesn't know when Summit will release it. It's the producers at Summit that does the trailer, not the director.
It is rumored that it will be shown during the Golden Globes that takes place January 17th, but we're not sure. Also, there was said to be a pre-screening of the uncut version of Eclipse... a couple of users on IMDB said that they saw a cut of Eclipse. I posted the link in the links section of this spot. To whether it is true, I'm not it's NOT true. Facts are being sorted out. I'll comment on my link to confirm if it is for real or completely false.
