This Friday the movie of choice is Super 8, yet another J.J. Abrams project by way of Steven Spielberg. Something escapes a train wreck while being transported from Area 51, and a group of kids catch some footage of it on a super 8 camera. Also out in extremely limited theatrical release (but available On Demand starting today; check your local interactive guide) is the Norwegian film Troll Hunter, about a group of students investigating a government cover-up of trolls in northern Norway. This one is a mocumentory in the Blair Witch style, Norwegian with English subtitles.
