“Avengers: Endgame” is set to be the culmination of every Marvel Cinematic Universe movie so far, and that means it is time for a movie marathon before heading back to the theater. First, fans should set up a viewing schedule, and then, they’ll need to find out where to watch the movies.

To watch all 21 pre-“Endgame” movies, first audiences should figure out a schedule. In order to watch one MCU movie per day leading up to “Endgame,” viewers should start “Iron Man” on April 4 if they are planning to go to the special Thursday night showings. They can start on April 5 if they are waiting for the actual release day on Friday. Those watching two movies a day can start on April 15.

Now that fans have a schedule, they need to figure out where to watch the movies. The theater is an option. Three AMC Theaters are running a 22-movie, 59-hour marathon leading up to “Avengers: Endgame.” However, those who prefer to pace themselves will want to find ways to watch at home.

With the exception of last month’s “Captain Marvel,” every MCU movie is available on home release. That means DVDs, Blu-rays and digital downloads are all available.

Rentals are also available for each Marvel movie released before 2019. Check out YouTube, Amazon, iTunes, Google Play, Vudu and more. Prices typically start around $2.99.

However, those looking to stream Marvel movies before seeing “Avengers: Endgame” will have a harder time. Netflix has a handful of the most recent movies, but the older movies are found in a variety of places. A few are only available on TV (networks are below, but check your local listings for times), and some are only on streaming websites that require a login from a cable provider. A few aren’t even available to watch without buying or renting.
