When Brody and Hooper take the latter’s boat out to search for Ben Gardiner’s boat, Spielberg displays his first penchant for using light to reveal mystery, danger and wonder, accompanied by John Williams at his airiest (musically it is about get heavy very soon). Like the rest of Jaws’ lighting scheme, it has a realistic light source — Hooper’s super-duper lamp — but set against the high-key look of the rest of the film, it has an otherworldly, sci-fi feel to it.
This light peering through the window of BG’s boat is maybe the most Spielberg-y thing in the whole of Jaws
When we cut to a wide, top shot of Hooper’s gadget-filled boat, the lights creating pools of yellow around the boat andturning the black sea a milkier blue. A retro reading might recast as Spielberg’s first space ship — a technological wonder filling a dangerous world with light and magic. Surely it should take off leaving a rainbow trail behind it?
