What actor would he look like? Who would play him in Conspiracies?

I know this may sound crazy but I have a few random choices. Gary Oldman in the Professional style, a younger, little bit taller Pacino from Devils Advocate, deniro maybe from a cape fear point of view, or even a mustache wearing Bradley cooper?

I always thought in a full cast, if have John goodman as abe, maybe a blonde mila jovavich as Gia, a younger Danny trejo for Julio, Rick moranis as Russ tuit (pronounced tweet, of course)...and jack.... I can never decide. Maybe a Tom hardy, Matt Damon, or Joseph Gordon levitt, but still not good enough

Has anyone ever mentioned Christian Bale as a possibility for RJ?

That's not a bad idea at all. But the way I have jack pictures in
my head may be impossible to find in Hollywood

Jeremy Renner as Jack,,,Robert Knepper [ prison break] as Roma..;-)

I was just talking about this a while ago! I think he would be a great as Jack.
