No, not a sequel to War of Worlds 2 but a World War 2 movie called "Valkyrie". It's based on the true story of military plot(Operation Valkyrie) to kill Hitler. Cruise will play Colonel Claus von Stauffenberg leader of the plot. It will be filmed in Germany in a key military location. It's something that is not well known unless you watched many WWII movies.
P.S.

Those were some of the heroes that tried to do the right thing but paid with their lives.
