This was shared by the Facebook Porsche in the movies page, and is a trailer for a 1980s Australian film called Freedom! It shows a young man fantasising about a Porsche 911 Turbo and a beautiful woman, while he’s playing a computer game (or at least that’s my interpretation of it).
There’s some wonderfully mad driving in the silver 911 Turbo, including getting it airborne and taking it off road, plus a cool soundtrack. Crazy stuff and a lot of fun to watch!
The Porsche gets written off in a spectacular crash and, looking at the footage, it looks like they really did crash the actual Turbo.
Update: I’ve just been told that the lead actor, Jon Blake, suffered a brain injury in a real car crash soon after making this film, and has since been unable to do anything but move his eyes. A tragic footnote.
