Think you're a huge fan of Marvel's movies — like "Iron Man," "The Avengers" and "Guardians of the Galaxy" — do you? Well, if you were a real fan, you'd be lining up for this 29-hour, 11-movie marathon they're putting on to celebrate the release of "Avengers: Age of Ultron," which runs through the Marvel Cinematic Universe so far — and poses a severe risk of triggering deep vein thrombosis — before culminating in the newest film. The first of such marathons takes place in Hollywood on April 20, but if you're willing to wait until April 29 you can experience it closer to home:

Oh, and the whole thing is sponsored by Cheez-Its and Kellogg’s Rice Krispies Treats, in case the whole "sitting in a movie theater for 29 hours" thing wasn't healthy enough on its own. And the whole thing will only set you back $70. So, you a real fan or what?
