I've received a couple of updates from readers who who have checked with their local theatres and found that not every theatre will be showing the Prometheus trailer before The Girl with the Dragon Tattoo.
Some are reporting that their local theatre is showing the trailer in front of Sherlock Holmes: A Game of Shadows, while others have found it's not showing until this weekend.
A word of advice to the readers: please phone around and check with your local theatres before you go to avoid disappointment. Some are showing it, some aren't.
