“Lord of the Rings” fans are lightweights. Marvel THIS!

AMC and Regal Cinemas announced a 29-hour Ultimate Marvel Marathon, a super test of stamina that’ll end with some of the first screenings of the new “Avengers: Age of Ultron.”

The marathon will begin at select theaters — some of which haven’t been announced — at 6 p.m. on April 29, and run through all 11 Marvel movies released since “Iron Man” in 2008, The Verge reports. The cinematic binge will cost $65, which comes out to just under $6 a movie, and give fans early access to the Avengers sequel that has received a lot of hype.
