Back when I was at college the film Gallipoli was released and I went with a few friends.
One of my friends, and myself were both interested in the history of WWI, and decided to go back the following week to see the film now we knew how it finished. Then one week later we went again!!
The film is brilliant (with a young Mel Gibson), but in a cinema the race against time is quite tense, which is why we ended up watching it 3 times.
