Gallipoli (1981) Ending

Gallipoli by Peter Wier
When Australian film director Peter Weir, perhaps best known to American audiences for Witness and The Truman Show, was planning his next film after completing Picnic at Hanging Rock (1975), he wanted a story set in France depicting the big battles of 1916-1917. A friend suggested he make a film about the Australian and New Zealand Army Corps (ANZAC) attack on Gallipoli. Unconvinced, he nevertheless traveled to Istanbul in 1976. After spending two days climbing the hills and wandering the trenches, Weir was struck by what he found: buttons, old leather belts and other items left behind by ANZAC forces. He decided then and there that he would indeed make a film about Gallipoli, saying, "I felt somehow I was really touching history."
His original idea was to tell a comprehensive story from enlistment in 1914 though the evacuation of Gallipoli near the end of 1915, but after several drafts, he was unhappy with the results. Instead, he decided to write a tale about two friends and their journey to war. The result is the outstanding anti-war film Gallipoli (1981).
