One of the greatest opening sequences?
The beautiful Lee Remick driving across the bay bridge, the great night shots of San Francisco, the flawless direction, and last but not least -- Henry Mancini's striking and unforgettable score... man, what an utterly great moment in film.
On a side note, Kelly passing by the Twin Peaks sign had me thinking of how much this may have inspired David Lynch's work; and before that moment came up, I was already reminded of Lynch.
