Vin Diesel himself let slip that he was talking to Scott about his "Hannibal" pic.Indeed.
Over on Diesel's facebook, the big guy writes "We talked about Hannibal and the Punic Wars and how by nature the story demanded three movies. The first movie centering around Hamilcar, Father of Hannibal and the Defender of Africa, in the First Punic War. He said he would get our friend Denzel to play Hamilcar. Haha, very super cool... Denzel is a friend, whom I admire and who has given industry advice that I use to this day. Him to playing Hamilcar and for Tony to Direct... exciting to say the least."
Now this "Hannibal the Conqueror" pic has been in development for the best part of a decade so don't go lining up for you tickets just yet.
UPDATE (10 August): I should have flagged the fact that Denzel Washington's name is being dropped as a candidate to play Hamilcar, which is all to the good.
