This looks fascinating.

It's a documentary exploring the legend, legacy and truth behind New Jersey’s infamous Action Park, a place once believed to be one of the most spectacularly fun amusement parks on Earth.

To some, Action Park was a place where unruly 1980s’ teenagers were given free rein on bizarre contraptions that seemed to violate both sense and the laws of physics.

To others, it was a death trap waiting to happen.

With unprecedented access to never-before-seen footage, documents and archive materials, we unearth the true story of the most dangerous and deadly amusement park in US history for the very first time.

Now here's an absolute treat for St Valentine's Day: truly, one of the most romantic films ever made. And the recent 4K restoration is a thing of great beauty.

David Niven and Kim Hunter are terrific together (and apart) as a bomber pilot who cheats death and appeals to a heavenly court for the right to stay on Earth with the woman he loves.

This wonderful film - where Earth is in glorious technicolour and Heaven is merely monochrome - is also a perfect introduction to the works of writer/directors Michael Powell and Emeric Pressburger, one of the great movie-making partnerships.
