A tired and weary looking Barry Pepper. War does that to people :(
As Colonel Hayes Hodges (played by Tommy Lee Jones) said to Major Mark Biggs (played by Guy Pearce) in the movie "Rules of Engagement (2000)": "I'll make you a deal right now. If you can tell me the average life expectancy of a Marine second lieutenant dropped into a hot LZ in Vietnam in 1967, I'll tell you everything I remember about Ca Lu."
Major Mark Biggs: "One week?"
Colonel Hayes Hodges: "Negative. Sixteen minutes. Sixteen fucking minutes, that's all I remember about Ca Lu."
