My Father the Hero

We love the movie and so do Australian high school students of French! Could you please let us know how to purchase the original DVD version (in French), preferably Region 4 so that we can watch it here? I am a French teacher and the old video copy that I have of this wonderful, fun and, as the students say, "cool" film is getting more than a little worn out. It is wonderful to see Mauritius which appears to be really beautiful in the film. I could easily enough purchase the American version but no thank you....the French one is so unreal. We love the story of the teenage girl coming to terms with the situation her parents are in as well as her first fling with a boyfriend. We're desperate to purchase this film on DVD!
