Jessica Shepard's promotion from Officer to Inspector, isn't as big a jump as it sounds. The SFPD, unlike nearly all other municipal police departments, does not have a traditional Detective rank. The Inspector rank is simply the next rank above Officer, and an Inspector's responsibilities are exactly like those of a Detective, in most other police departments.
Mark Pellegrino and Titus Welliver co-star in this movie, both on the same side of the law. Later, they would co-star in the television series Lost (2004), where they would play opposing sides in the island's good and evil mythology, as Jacob (The Man in White) and The Man in Black.
Well-known San Francisco bars and restaurants in the film, include Tosca Café and Vesuvio, both on Columbus Avenue in the North Beach district, as well as Red's Java House, at Pier 40 on the waterfront. Several scenes were also filmed at the Palace of Fine Arts, with its unmistakable rotunda and lagoon.
Jessica Shepard's final confrontation with the villain, was filmed at the San Francisco Maritime National Historic Park. The ship behind her is the Balclutha (1886). She was acquired by the San Francisco Maritime Museum in 1954, and designated a National Historic Landmark in 1985. Two of her three square-rigged masts, and their lower yards, are clearly visible behind Jessica.
