Your chance to be a part of Marvel movie history

Want to be in a Marvel movie instead of just watching one? The grand-prize winner of the Be in a Marvel Movie sweepstakes wins a walk-on role in a future Marvel Studios movie. (Though the fine print warns there’s no guarantee the winner will appear in the finished film after the editing.) Three first-prize winners will win a collected edition of Marvel comics and 15 second-prize winners will get a 12-issue subscription to one of Marvel’s titles. Go to marvel.com to enter. Deadline is Aug. 10.
