No, no ... Luca Brasi was very much still alive when Vito secured the film role for his God-son, Jonny Fontaine.
Luca did not have his Final Meeting ... with Sollozzo and Bruno Tattaglia ... until several scenes later.
You sure? Because I thought that Luca was very much dead and sleeping with the fishes by the time of the Khartoum incident (and I thought Rocco was the one who got Khartoum's head in Woltz's bed). I know that he did the "band-leader", but I don't think he got back at the bigoted pedophile of a director.
And Luca Brasi, in the books, forced a midwife at gunpoint to throw his own illegitimate newborn daughter in a bakery oven after murdering the mother. Why? Because they were Irish and "none of that kind should live".
He was an absolute
monster in the books, and even
Vito was terrified of Luca's pure psychopathic nature; the only reason he followed Vito unconditionally was because the Godfather rescued him from a death penalty for butchering a cop. If he wasn't a Corleone, he'd be an irredeemable villain, and Mario Puzo showed the line that Cosa Nostra crosses in their dealings and how it's not a glamorous job, knowing, in spite of all of the money, drugs, and women the mobsters got to partake in, they'd all end up dead prematurely, in prison for life, or worse off than they were before they became made.
