We can also reveal that filming on the Sopranos prequel is set to begin in early March of 2019, so casting announcements will be forthcoming over the next couple of months!

Young Tony

Of course it wouldn’t be a Sopranos project if Tony weren’t involved. The Many Saints of Newark will seemingly take place over the course of several years and the studio will be looking to cast multiple actors in the role of Tony. When the film begins, Tony is a first generation 9-year old boy with a passion for the Yankees. The film will follow Tony to age 16 where he is described as a “budding linebacker” with long hair and bellbottoms. According to Sopranos’ canon, Tony was born on August 24, 1959, so we can look forward to seeing the film take place between 1968 and 1975.

This setting would find Tony’s father, Johnny Boy, and his Uncle Junior in their primes working under Dominic DiMeo, the original Boss of the DiMeo Familiy that Tony eventually led. It would also take place near the death of a character that was the inciting factor for a key relationship of the original series…

Dickie Moltisanti

A foot solider for the DiMeo family, Dickie was a minor character in the series, but it was his death and subsequent absence that lead Tony to take in and mentor Dickie’s young son, Christopher. Dickie will be a young man here and while he’s not among the characters we have found out about, it’s almost a certainty that a young Christopher will be present here.

Canonically, Dickie is the first cousin to Tony’s wife, Carmela, and his wife, Joanne, is a Blundetto, making their son Christopher a cousin to the Blundettos, just as Tony is. After Dickie’s death, Tony took care of Christopher, calling him his nephew, though Christopher’s longtime girlfriend Adriana indicated that Christopher and Tony did have a blood relation. In this film, Dickie is described as Tony’s uncle, and a new character may reveal the blood connection described above.

Aldo Moltisanti

By all accounts Aldo Moltisanti is an entirely new character and, presumably, the link to the blood relation of Christopher and Tony. Described as an “elegant wiseguy” in his mid-60s, Aldo is revealed as Tony’s grandfather! The implications here could be huge. We know (or at least we think we do) that Tony’s father, Johnny Boy Soprano, was one of 3 sons born to Corrado and Mariangela Soprano. However, little information is known about the familial connections of Tony’s mother, Livia. In the film, Aldo is newly married to 24 year old Giuseppina Bruno, leaving us guessing as to whom he was previously married and what it might reveal, if anything, about Tony’s lineage.
