Based on real people
Or are they just types?
Dano = Downey Jr.?
Keitel = DiPalma
Caine = Philip Glass??
Or am I making too much of how much Q Man sounds like Iron man, and the bloody woman in Keitel's vision who looks like Carrie?
I know this is a superficial question for what was a relatively deep movie about age, art, loss and love, but what's so wrong with a superficial question?
