A Rizzuto movie would be pretty cool, but, it's probably too soon. I'd (unfortunately) give it another 10-15 years. Too many people who would need to be portrayed are still embroiled in the life and probably ongoing investigations in Montreal. I suppose you could do a movie more about Nick than Vito but even then there's a ton of overlap, it'd be hard to do. Not to mention such a movie would be inviting fair comparisons to The Godfather -- having a multi-generational mob flick wherein leadership is passed through hereditary succession -- in any case, good luck selling a movie set in Canada to American and European audiences. Nobody who isn't already a mob enthusiast cares much about a mafia faction in Quebec.

Besides, there's still a lot of untouched history from New York. Although, personally, I would love to see a movie based in Italy during Toto Riina's reign.
