Bunker77 is worth an hour and a half of your time if you're into 60s/70s California/Hawaii surf culture with a bit of Hollywood thrown in.
It's the rich to riches story of Bunker Spreckels, heir to a sugar fortune and the stepson of Clark Gable. His dad & Gable both die while Bunker's in his teens; his mum has a new baby, (Gable's, so the press go nuts about it/her) and Bunker's left pretty much to his own devices for most of his teens.
As his dad had close connections with the King of Hawaii, Bunker moves to the North Shore of Hawaii, gets mentored by local surfers - very rare for a white kid. He then turns out to be a surf god. He invents/shapes his own boards that are incredibly short and fast, surfs waves that none else has and looks like an alien.
Then on his 21st birthday, he inherits all the money and goes completely fucking mad with it
He becomes a rock star, an actor, a martial artist, a skateboarder, an even more incredible surfer and takes all the drugs all the time. Loads of dubious decisions (eg hanging with Nazis in South Africa c.73/74) but he packed a lot in tbf. His whole life was filmed, including screen tests for the part of Lucifer for Kenneth Anger that Anger later compiled into 'My Surfing Lucifer'.
Footage of the times is amazing. Tarantino must have loved all this source material for Once Upon A Time In Hollywood.
