A scene from Mank (2020), starts with a thick script hitting the table. A camera tilts up to show Charlie Lederer standing and holding a hat. Then a wider angle shot reveals Herman is sitting in a chair. Charlie Lederer is standing opposite to him and Rita, with binoculars, is birdwatching:
Charlie Lederer: What can I say? She's my aunt
Herman: Oh, it's not about her, it's about him. Or rather, it's him, but it's not her.
Charlie Lederer: The lonely showgirl, trapped in a castle, doing jigsaw puzzles.
Who exactly is "him" Herman referring to?
