The pic is currently untitled with Allen writing, producing and directing. Story details are also being kept under wraps.
Deadline Hollywood was the first to report the news.
Sources say Stone will likely be a part of a large ensemble which is currently casting with production set to start this summer in Spain.
Stone’s slate of upcoming projects includes the comedy “Birdman,” which is currently filming, the untitled Cameron Crowe pic with Bradley Cooper and Rachel McAdams and the Legendary horror pic “Crimson Peak.”
While it sounds like busy sked, sources add that both “Birdman” and the Allen project aren’t expected to be long shoots, nor is the Crowe project, and “Crimson Peak” doesn’t shoot till January.
