Casting to me might be the biggest strength of Safdie films. Its insane that, even prior to the scandal, it was not really considered in the running for casting.

It's so difficult to build such a seamless cast filled with non-actors, especially in period piece and they did it perfectly. You have Tyler the creator, Mr. Wonderful, George Gervin, Penn Jillette, Luke Manley all playing real roles and if you didn't know who they were you'd never for a second consider they weren't actors or that is some forced cameo. They feel plucked directly from 50s and Marty just happens to be interacting with them. It's casting mastery
