Denzel Washington is in the picture as Luisa Rey's dad.
Seriously, it's gotta be him, the guy on the right is also in the film as a multiple role character, I want to say Hugh Grant but I really am that lazy to hit alt back and check. But I did a word search for denzel in the trivia and it isn't in there.
If you have this on a digital copy it's at 1:50:57/2:51:57 right as the other black guy, who plays the head slave of one of the earlier stories, maybe even the earliest one. He (as the actor in a new role) breaks into Luisa Rey's (Halle Berry) appartment, he says hes the one next to her dad, Korean War.
Seriously, that's Denzel, or maybe I misinterpreted it, when he says it's "him on the end next to her dad" being him, on the very end, whatever the case, Denzel is on the far left of that black and white pic. Or am I really the racist white dude who mixes up Cosby and Obama right now? I would bet anyone like maybe a hundred bucks, thats pretty sure. But not certain, and it's not on any other trivia with a quick Google search. But I paused it for a solid 5 minutes, and I'm like dead certain it's him.
