Now that The Intouchables has made $339.5 million overseas, Omar Sy is finally letting himself think big. ''Growing up where I did, I never allowed myself to dream of being successful,'' says the actor, 34, who was raised in a housing project outside Paris like the one his character (a caretaker for a paralyzed aristocrat) inhabits in the film. In February, Sy who names Chris Rock and Denzel Washington as inspirations became the first black performer to win France's César award for Best Actor. A Hollywood career might be next, but first Sy wants to polish up his schoolboy English. ''If I had known I'd be coming to L.A. someday,'' he says with a laugh, ''I would've paid more attention in class.''
