Welcome, SNJ!
The "you've found your Luca Brasi" scene that you're referring to appears in the novel. Hagen, not Vito, made that statement to Michael. Much as I don't like to disagree with my friend Goombah, I don't recall it in the Saga.
TB, I'd hate to challenge you on anything GODFATHER, but I too recall Vito saying to Michael, "I think you found your Luca Brasi." Perhaps it was in THE GODFATHER EPIC, which was released on vhs in the early 80's. I believe I still have mine in one of my storage units. I'll be sure to check.
