Nothing says a director is growing quite like jumping from a Hitler biopic to a biography of one of the most beloved princesses the world has ever known.

That’s the trajectory for Downfall director Oliver Hirschbiegel, as he begins to prepare his upcoming Princess Diana biopic, Caught In Flight, now with a brand new actress. Deadline reports that Naomi Watts will be starring in the film, replacing Jessica Chastain. The film is currently being sold at the Berlinale, so more news on this project should be coming fast.
