Having lived in San Francisco, I've walked across the Golden Gate Bridge and driven across it countless times. The bridge is a nearly perfect metaphor for what some people go there to do. The view on a clear day into the city, the red painted cables glowing in the sun, the sudden way the fog comes in off the ocean to envelop the bridge, the path from the cold city to the warmth of Marin County. Death too is beautiful, dramatic, mysterious, abrupt, and an escape to another place.
In The Bridge, a film about the Golden Gate and suicide, director Eric Steel makes effective use of the bridge's imagery and its relation to death; you can see why so many people choose to end their lives there. The footage he and his crew got is astounding at times...families discuss the death of a loved one while that same person is shown pacing back and forth on the bridge, thinking, waiting. You see a group of police officers, looking almost bored (which was probably hyper-aware nonchalance), talking a man back over the railing.
And yet, I can't tell if that footage actually added anything to the discussion of the issues of mental illness, depression, and coping which were at the heart of many of the jumpers' problems. Does watching death make it any more understandable to family members. To audience members? The footage doesn't say why, it just shows us how, and those aren't quite the same things.
Here's an earlier post on The Bridge, a graph of suicides by location on the Bridge, and the New Yorker article by Tad Friend that inspired the film.
