First of all, you MUST finish the game and unlock the theater in order to move on to the next requirements, as the current requirements have changed from those in the Master Collection (I will later provide a guide on how to unlock it in the Master Collection).



·Once you unlock the theater, you will be able to see several scenes, but we are going to focus entirely on the EVA scenes.
These are the key scenes:

·First scene, first encounter, and introduction of EVA. I recommend watching it all the way through, including the ambush by the Ocelot unit (yes, that scene where he's changing right under our noses, lol).



·The second key scene would be the reunion in the mountains where he gives us the key before fighting The Fury.



·The key final scene would be the reunion behind the waterfall.



·Once you've done this and watched those scenes a couple of times, I recommend leaving and re-entering the theater, and it will appear at the top.



·I hope this has been helpful. It may seem silly, but it's what makes this game unique and charming. By the way, the pink theater will always be available in your Plus game, and you don't need to collect all the scenes in the game; you can go straight to unlocking it. Now that the guide is over, here's a video showing what the scenes are like.
