Army Sgt. 1st Class Phillip Kennedy Johnson is the author of graphic novel “The Last Sons of America.”

A gritty future where nobody in the U.S. is able to have children after a biological terrorist attack will soon be brought to life as a Netflix original movie starring “Game of Thrones” star Peter Dinklage — all from the imagination of an Army sergeant.

Based on the post-apocalyptic graphic novel “The Last Sons of America,” which Sgt 1st Class Phillip Kennedy Johnson wrote while serving as a trumpet player with the Washington, D.C.-based U.S. Army Field Band. The adaptation will be produced by Matt Reeves, writer and director of the upcoming Warner Bros. film “The Batman,” Netflix announced earlier this month.
