The movie and the bravery notwithstanding, I'd suggest it was the achievements of the ANZAC on the Western Front that should be remembered most of all.
Gallipoli was opposed by too many powerful forces in the U.K. to succeed and I've no doubt was betrayed before it even began. It's not inconceivable in fact that the likely outcome was well known to those in authority and winked at with the operation simply used for mostly political purposes. Recall that the Ottoman Turks had a long and cosy relationship with certain elements in the UKwhich not even the atrocities of the 1912 Balkan War or WWI seem to have affected, much less subsequent events.
