Do you have 27 hours to spare before Avengers: Age of Ultron hits theaters? If so, take a shower, bring a blanket and get ready for the Ultimate Marvel Marathon: a 29 hour, 11 movie marathon that begins at 6pm April 29 with Jon Favreau’s Iron Man and goes until around 10pm April 30 with an early screening of Avengers: Age of Ultron. AMC and Regal are each hosting similar events and you can read more below.

Here are the links to info for the Ultimate Marvel Marathon at AMC and Regal. Not all locations and tickets are on sale, but that’s where you’ll find the info. It looks like the ticket is $65 per person, which breaks down to just under $6 bucks a movie.

Here’s the tentative schedule for the Ultimate Marvel Marathon:

6:00pm IRON MAN

8:25pm THE INCREDIBLE HULK

10:35pm IRON MAN 2

1:00am THOR

3:10am CAPTAIN AMERICA: THE FIRST AVENGER

5:30am THE AVENGERS

8:48am IRON MAN 3

11:15am THOR: THE DARK WORLD

1:45pm CAPTAIN AMERICA: THE WINTER SOLDIER

4:20pm GUARDIANS OF THE GALAXY

7:00pm AVENGERS: AGE OF ULTRON (RealD® 3D)

Here’s the poster for the Regal version of the event. AMC has one too, but it’s much smaller.

Also of note, several theaters are hosting double features of The Avengers and Avengers: Age of Ultron which is cool, I guess, but really you should watch Captain America: The Winter Soldier before Age of Ultron. That would be a more cohesive link. But I understand the obvious booking of the first film and its sequel back to back.
