I saw a documentary on youtube a few years back. The Bridge - It was originally intended to be a year of film footage of the Golden Gate bridge. Though when the film makers saw the amount of suicides attempted - and taking place, the documentary changed direction and theme.
It tells the backstory of certain people who jumped from the bridge. Nearly all died. From memory I think they interviewed one survivor, who was pushed to the top of the water and saved by seals. The film crew also spotted potential jumpers, called the authorities and saved a few lives.
A strange documentary. Not one I'd watch again. Not a "date movie"
