John Cox, who has projects in development at the USA Network and ESPN, has been tapped by by Joel Silver for Warner Bros. Pictures to write SGT. ROCK, an adaptation of DC Comics' World War II adventure comic, according to THE HOLLYWOOD REPORTER.
Sgt. Frank Rock was the leader of his infantry unit called Easy Company. He first appeared in a 1959 issue of OUR ARMY AT WAR. As the characters popularity rose, the comic was renamed SGT. ROCK in 1977 and ran until 1988.
