Been watching it here and there the past week. Noticed two more callbacks to Marty's past films. Sorry if these were already mentioned.

The guy who tries to shoot Hoffa in the courtroom has the same body language as the kid who shoots the guy in the restroom in Mean Streets, when he's walking up to Hoffa. Hands in coat pocket walking up, same seamless facial expression, etc.

When Hoffa and Buffalino have the argument at Sheeran's formal event, just as Hoffa walks off and strands Russ there the Gold Diggers sing "The Time Is Now". Remember when Michael shoots Charlie, Johnny Boy and Theresa in Mean Streets he says, "Now's the time!" before his gunner (young Marty) opens fire.
