"I've only scratched the surface. I think that there's another chapter here," the actor said Monday while appearing on BBC Radio 4's Today program. Oldman previously appeared as Churchill in 2017's Darkest Hour.
"Maybe a movie, maybe something on television," Oldman continued.
Oldman also said on Monday that he has started working with Churchill's great-grandson Lord Randolph Churchill on adapting a 1947 short story that was written by the politician titled The Dream.
"I've been talking about maybe doing it as a sort of two-hander onstage," he said.
