If you’re a Marvel fan and preparing for Avengers: Age of Ultron, chances are you’re thinking now is a good time to start revisiting the MCU movies — in order, obviously — before May 1. AMC and Regal are here to help you out with that with their massive Marvel movie marathon, all leading up to the premiere of Avengers: Age of Ultron. Here’s the thing, though: you’ll be watching every one of these movies in one sitting, so you should probably bring one of those donut-shaped butt pillows.

For $65 per person (that’s about $6 per film), you can watch all 11 movies, including Age of Ultron. The event begins on April 29 at 6PM and continues through April 30, with an early screening of the Avengers sequel at 7PM.

You probably just did the math, but if you’re bad at that sort of thing, that’s 29 hours of Marvel movie entertainment. Almost 30 hours in a movie theater. How much popcorn can one person consume in that time period? If you have $65 and commitment, you can find out.

Here’s the full lineup:

Tickets for all theaters and events are not yet on sale, but you can get the proper info by visiting the official AMC and Regal websites.

For the rest of you, Avengers: Age of Ultron hits theaters on May 1.
