Tarantino is known for his blood-soaked films "Reservoir Dogs," "Pulp Fiction" and "Kill Bill."
The BBC said Tarantino plans to move into pre-production on his latest project soon.
"You're talking to a real happy dude right now," the filmmaker, who completed his latest screenplay last week after several years of writing, said at the Provincetown Film Festival. "I didn't know everyone knew about it, so this is actually kind of very bizarre for me."
The war movie will be the director's sixth major feature.
"I don't want it to feel like a period film. I want it to feel current. I want it to feel right now. One of the things I have to battle against is 30 years of Nazi-occupation TV movies where we've all seen the big streets and the vintage cars and the Swastikas, and we've just seen that ad nauseum. This is a modern, in-your-face movie. This is not a TV movie period piece," Tarantino said.
