Rather than the Darkest Hour, the new movie is already looking like it will be the British star's own finest hour.
After years of awards snubs and disappointments, it looks almost certain that the Academy will follow the BAFTAs and give Oldman his first Best Actor Oscar this Sunday.
Unsurprisingly, the actor himself may not be ready to say farewell to Winston Churchill.
In a new interview he reveals the idea for a sequel set at the 1945 Yalta Conference after World War 2 and givng the tantalising possibility that his towering performance could be matched by new on screen incarnations of the equally iconic US and Russian leaders.

In the latest Hollywood Reporter interview, Oldman explained how close he came to not accepting the role at all.
He said: "Racked with insecurity. I turned down Churchill many times. And didn’t want to do it. Didn’t want to go near it. And, ultimately, I think it was fear. And you’re walking in the shadow of [others]."
After it resulted in the greatest accolades of his acreer, he happily discusses where the story could go next: "At the end of the war, there’s the summit with Stalin... And so that is another. Yeah, you know, we might. And we’d get someone. Roosevelt’s a great character, he’s on his way out there isn’t he? Yeah, so maybe. But I need a break from the makeup chair.”
