Thunderstruck

In terms of genre, this is a cross between a road movie (a drive across Australia by 4 men) and a comedy.

But to appreciate this film, you probably need to know a lot about Australia and its culture and a reasonable amount about the rock group AC/DC, especially their early years. So probably the ideal viewer is a middle-aged Australian! I suspect other viewers simply may not understand the jokes nor recognise the many Australian actors and non-actors in cameo roles, that make the film such a delight.

The pilgrimage to the grave of Bon Scott's grave is a real-life phenomena, with thousands of people visiting the grave every year, and apparently this film has contributed to even larger numbers of ACDC fans making the trip, so life does imitate art!
