Cosi
It's a who's who of Australian cinema, but you wonder what attracted them all. A young man agrees to produce a performance of the opera Cosi Fan Tutte in a Sydney mental asylum, and that's about it.
Presumably the premise was meant to set up hilarious mental health hijinks and some good lines and situations comes out of the proceedings, but the script is very dry, the plot meanders and goes really nowhere, and nobody seems to be trying very hard. Some of Australia's best acting talent wasted.
