Arguably one of the best flicks shot in San Francisco—our money is on Vertigo or the yet to be filmed or even conceived Shooting Versace In Style: The Andrew Cunanan Story—the film version of David Goodis' Dark Passage will screen in Presidio Park on Saturday. And you must attend! And dress warmly! As the public viewing of Humphrey Bogart and (talented but infamously difficult-to-work-with) Lauren Bacall's third cinematic pairing is not to be missed.

What's it about? Glad you asked.

Convicted murderer Vincent Parry (Humphrey Bogart) escapes from San Quentin and goes on the lam to try to prove his innocence. He accidentally meets Irene Jansen (Lauren Bacall), who takes him in and becomes his protector. Before Parry undergoes plastic surgery to change his appearance, his face does not appear on screen. Following surgery, when the bandages are dramatically removed, lo and behold, he looks exactly like Humphrey Bogart! Filmed almost entirely on location in San Francisco, including a decidedly tense moment on the Golden Gate Bridge, the film is a classic moody, romantic film noir. Director Delmer Daves, a San Francisco native, filmed in his beloved city by the Bay.

It also features one of the greatest San Francisco apartments ever put to film. Sure, those scenes could've been shot on a soundstage, but still! So alluring in its simplicity is Becall's pad. Ahem. Anyway, details are as follows.
