"For a coup to be successful you need tanks. My tanks" declares tank commander Peter O'Toole to idealistic young army officer David Hemmings in this engrossing military drama reminiscent of Bunuel's 'La Fievre Monte a El Pao' and Jancso's 'The Red and the White' with a wonderful punch line as he demonstrates to Hemmings that power comes down the barrel of a gun and you never know who's next for the firing squad.
