 Brewer told a Channel 5 website writer that the rain was the biggest challenge of the night shoot , as it was " beyond freezing " . She also revealed that she ran in shoes that she had not broken in and they made her feet bleed . The actress added " It was incredibly stressful but I guess it was stress in a good way . There were months of preparation involved so that it could run like clockwork . So I guess it was stressful in the sense the emotional stakes were heightened for a two @-@ week period . It was exhausting and I think we can all say we were happy once it was over . But the final result was worth it . " McGregor filmed his final scene out of sequence at the Melbourne studios . He explained that they had already shot Mark 's last scene on location , then went back inside to do the studio shots . He revealed " The final thing I filmed was a conversation between Mark and Kyle , where they 're saying goodbye . It was a bit sad , but it was basically just these two guys hugging each other – with the cast and crew watching ! "
