The "Lincoln" director previously collaborated with Kubrick on 2001's 'Artificial Intelligence'. The project was conceived by Kubrick in the 1970s and later written and directed by Spielberg, the Hollywood Reporter said.
"I've been developing a Stanley Kubrick screenplay for a miniseries -- not for a motion picture -- about the life of Napoleon," Spielberg told French TV network Canal+.
Kubrick, regarded as one of the greatest filmmakers of all time, directed groundbreaking films like '2001: A Space Odyssey', 'Barry Lyndon', 'Lolita', 'The Shining', 'Dr Strangelove', 'Full Metal Jacket' and 'Eyes Wide Shut'.
In 2011, a book 'Stanley Kubrick's Napoleon: The Greatest Movie Never Made' was published.
The perfectionist director had offered actor Oskar Werner the title role of the French emperor while actress Audrey Hepburn had decline a part in the movie, politely writing, "...Will you please think of me again someday?"
Kubrick died in 1999 at the age of 70.
