AMC and Regal theaters will host 27-hour Marvel movie marathons ending with The Avengers: Age of Ultron late next month.

The marathons will play every Marvel movie in order starting April 29 at 6:00 p.m. local time. The marathon will continue through Thursday, April 30 with The Avengers: Age of Ultron beginning at 7:00 p.m. (meaning you get to see the film a little early!).

Here’s the film-by-film breakdown:

6:00 p.m. IRON MAN

8:25 p.m. THE INCREDIBLE HULK

10:35 p.m. IRON MAN 2

1:00 a.m. THOR

3:10 a.m. CAPTAIN AMERICA: THE FIRST AVENGER

5:30 a.m. THE AVENGERS

8:48 a.m. IRON MAN 3

11:15 a.m. THOR: THE DARK WORLD

1:45 p.m. CAPTAIN AMERICA: THE WINTER SOLDIER

4:20 p.m. GUARDIANS OF THE GALAXY

7:00 p.m. AVENGERS: AGE OF ULTRON (RealD® 3D)

This Avengers marathon sounds like the ultimate way to pay your respects to the Marvel Cinematic Universe and will surely test the mental strength of even the most diehard fans. I always wonder how people are feeling by the end of one of these marathons. Will your brain be able to function once Age of Ultron rolls around? Do you take a nap during Thor or The Incredible Hulk to help deal with the inevitable fatigue?

With Ultron beginning on Thursday, April 30 as part of the marathon, we suspect that many theaters will run marathon-less Ultron showtimes around the same time. This means you’ll be able to catch the film a bit ahead of its May 1 opening.

Ticket prices for the “Ultimate Marvel Marathon” aren’t yet available. We checked a few local theaters and couldn’t find tickets, but keep checking AMC and Regal’s websites.
