Maybe not the best movie-promotion idea: In Jefferson City, Missouri, a movie theater known for having actors portray characters from popular films did the same thing with &amp;#8220;Iron Man 3.&amp;#8221; But not everyone was aware of this promotion, as people called into police after spotting a man wearing full tactical gear and a fake gun in the parking lot&mdash;and police treated the situation as an active shooter situation. Less than a year ago, James Holmes was suspected of opening fire in a Colorado movie theater during a midnight screening of &amp;#8220;The Dark Knight Rises.&amp;#8221; &nbsp;(photo via Amber &amp;amp; Amanda Photography&amp;#8217;s Facebook page)
