Alberta Film Ratings has revealed that the upcoming Guardians of the Galaxy trailer will have a runtime of 2:23. The rating of the trailer (not the film) is also said to be PG. With this news, the first trailer may be soon on the way. Does this mean it will most likely be attatched to copies of Disney's Muppets Most Wanted next month or RoboCop this Wednesday?
