Jessica Shepard's promotion from Officer to Inspector isn't as big a jump as it sounds. The S.F.P.D., 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.
Internationally, the movie was renamed through multiple titles. Including "Blackout," "Stalked," "I Can't Believe It's You," "Murderous Instincts," "Unexpected Twist," and "An Eclipse." Additionally, "Blackout" was the film's original title during production.
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, built in 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.
Filming San Francisco practically earned co-star credit, so director Philip Kaufman fought to shoot the movie in the city he knew so well. 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 30 on the waterfront. Several scenes were also filmed at the Palace of Fine Arts, with its unmistakable rotunda and lagoon.
According to Philip Kaufman, it was Ashley Judd's idea to cut her hair short for the movie because she believed that's the way a cop would wear it. While she promised the director that her no-frills do would allow her to make it to the set in 10 minutes flat, it felt more like 15 minutes.
