The British star portrays Long John Silver in the latest movie adaptation of the tale and he has revealed that a follow-up is already in the works.
He says, "One has to be careful. I can't reel off a list of sequels to literary classics that have done well, but that won't stop us. We're already working on it.
"It'll probably be set in the Mediterranean so we can work in the Barbary pirates."
And giving up a few plot pointers, Izzard tells TV Guide, "Only four of us are left alive at the end of this one (first film), but there are new places we can go, especially with the relationship between Jim (Hawkins) and Long John. They're buddies, they're foes, they're like mentor and student or father and son. Long John loves Jim but is also prepared to kill him. I think they have big adventures ahead."
