VIN DIESEL may now have backing for his proposed film(s) on Hannibal: Vin Diesel Says A Studio Is Interested In Making His Hannibal Trilogy (Denzel Washington Still In?) (IndieWire Shadow and Act Blog).
My understanding is that Denzel Washington has been slated to play Hamilcar, Hannibal's father, not Hannibal himself.
Diesel has been talking about this project for some years, and his Facebook comment does seem to imply that he now has studio backing for it. I hope so, anyway.
