“Mafia Inc” was officially inspired by a nonfiction book on the Canadian mob. The movie and its characters are fiction, though, and their unofficial inspiration appears to be other mob films. It takes brass to poach on turf decisively owned by “The Godfather” and “Goodfellas,” and the director, Daniel Grou, who goes by Podz, deserves credit for delivering a saga that’s never dull despite hitting overfamiliar beats.

Sergio Castellitto plays Frank Paternò, a Montreal crime boss whose latest venture — a share in a bridge that will connect Calabria to Sicily — could make him legit. Frank has two sons: Giaco (Donny Falsetti), who has shades of Sonny Corleone (he disagrees with his father in front of associates), and Patrizio (Michael Ricci), who is engaged to Sofie (Mylène Mackay), the daughter of the family’s wary longtime tailor (Gilbert Sicotte).

There is also Vince (Marc-André Grondin), who, we eventually learn, is almost like a son to Frank, although the way he is introduced — arranging for a bus carrying a youth soccer team to be driven off a cliff in Venezuela — makes the revelation of his ties even more horrifying. Who would welcome such a psychopath? Was he always that way?

Apart from the multilingualism (the strong cast moves fluidly among French, English and Italian), the cruelty and ingenuity of the violence are what most distinguish “Mafia Inc,” which can be tough to watch even for this genre. For better or worse, Grau has a knack for staging brutality, and for having his movie rock out to a Joy Division track or two.
