Well, maybe take the day off? AMC have announced they will be having a massive Marvel movie marathon. The popular theater chain will play all 22 movies, spanning from 2008's Iron Man to the newest movie coming out, Avengers: Endgame. How much time will this be you ask? 59 hours! Alamo Drafthouse have also announced a similar marathon.
This means you’ll need to sit through 56 hours of movies before you see that final showdown with the big bad, Thanos. Just maybe take a couple bathroom breaks if you can. Good luck.
