More people choose to end their lives at the Golden Gate bridge than other other place in the world. A couple of years ago I read an article about this fact in the New Yorker titled, Jumpers by Tad Friend.
The article inspired director Eric Steel to film the Golden Gate Bridge for a year. His film crew caught 23 suicides, missed one and also recorded a man saving a girl from jumping by grabbing her jacket and physically pulling her off the edge of the bridge. They also captured a failed attempt when a boy survived his jump and was kept afloat by a Bay Area seal until the coast guard arrived to rescue him.
The camera crew vigilantly called the bridge authorities when they observed clear signs of someone about to jump. In doing so, they foiled six near suicides.
Steel took criticism for the film after he lied about his intentions in order to get permission, saying it was a documentary about a day in the life of the Golden Gate Bridge.
The film is called, The Bridge (trailer). It first aired in September 2006 and was released on DVD June 12th, 2007.
San Francisco columnist Violet Blue gives a very interesting review of the film and includes a Q & A mp3 with director Eric Steel.
