Guardians of the Galaxy Bonus Scene Not For Critics

During our screening of Guardians of the Galaxy, our reviewer was surprised that he did not see a bonus scene after the credits since it has become a Marvel tradition. Director James Gunn confirmed to me that there is indeed a scene but it will not appear until opening day and will not be part of any of the advanced screenings. Sounds like a reason for those who have already seen it and loved it to venture out this weekend and catch it again.
