Bustin' Down the Door

Bustin' Down The Door is a 2008 documentary film chronicling the rise of professional surfing in the early 1970s. The film follows a group of young surfers from Australia and South Africa, including Shaun Tomson, Wayne 'Rabbit' Bartholomew, Ian Cairns, Mark Richards, Michael Tomson and Peter Townend, as they relocate to Hawaii encountering obstacles, turf wars and massive wipeouts along the way. Clashes with the locals, some of whom find the newcomers' bravado to be insulting to Hawaiian culture, eventually culminate in death threats against the subjects of the film.
