If you feel like you need to prepare yourself for Marvel Studio’s Avengers: Infinity War in the most epic way possible, AMC Theaters has got you covered. On its website, the theater chain announced the “Avengers: Infinity War Marathon,” which will run for a whopping 31 hours.

The marathon will likely start out with 2008’s Iron Man, the Marvel Cinematic Universe’s first film, and conclude with Avengers: Infinity War, the franchise’s 19th movie. However, the website does not list any information beyond a runtime and date, so that is purely speculative at this time. AMC Theaters has yet not unlocked the option to purchase tickets to the Avengers: Infinity War marathon on its main or affiliate website.
