WATCH: Google + Premieres Lincoln Trailer During Glitchy Q&A With Spielberg And Gordon-Levitt

Steven Spielberg debuted the trailer to Lincoln, his highly anticipated film about the 16th U.S. President at 7 p.m. on Tuesday, but the experience was less-than-mesmerizing. That's because the webcast was initially plagued with glitches that left some viewers with nothing more than a "buffering" notice or moments when the trailer seemed to fade in and out of blackness.  The Google + Hangout session with the filmmaker and Joseph Gordon-Levitt, who stars as Lincoln's son Robert Todd Lincoln, was also bedeviled by sound problems that turned the question-and-answer session into an annoying echo chamber.  If you didn't — or couldn't — see the trailer during its premiere, check it out after the jump, along with the first images from Spielberg's '12 Oscar contender.  more »
