Tropic thunder

Summary: Watch John 'Four Leaf' Tayback as he fights a gruesome battle during the Vietnam War. But, this is actually a scene from 'Tropic Thunder,' a big-budget adaptation of Tayback's wartime memoir. Starring as the central platoon are Speedman, Lazarus, Chino and Portnoy, as well as young character actor Kevin Sandusky. To play the character of African American Sgt. Osiris, Lazarus dyes his skin dark and refuses to break from character. When a scene goes awry, the film's director, Damien Cockburn goes off. With filming a month behind schedule only five days into shooting, the real 'Four Leaf' takes Cockburn aside and suggests that he drop the actors in a real jungle and use hidden cameras to capture the action. Chaos and insanity ensue
