According to TV Guide, Eastwood will direct an adaptation of the book "Flags of Our Fathers: Heroes of Iwo Jima" for Spielberg's company DreamWorks.
The book was written by James Bradley (search) — whose father was one of the six soldiers who raised the flag at Iwo Jima — and Ron Powers.
The battle of Iwo Jima in February-March 1945 was crucial for both sides. The Volcano Islands, which include Iwo Jima, were 700 miles south of Tokyo and part of the capital prefecture — thus the first part of Japan proper to be invaded.
The Americans wanted its three airstrips as a way station for long-range bombing raids on Tokyo, and for the invasion of Okinawa.
Mount Suribachi, a 550-foot dead volcano at the tiny, teardrop-shaped island's southern tip, was where five Marines and a Navy corpsman raised the flag on the third day and were captured on film by Associated Press photographer Joe Rosenthal.
