Sean Connery was rumored to have asked the production to build him a cabin on Alcatraz so that he wouldn't have to travel to the mainland every day. In reality, Connery allegedly did ask permission to anchor a yacht off the dock of Alcatraz but was denied by the Coast Guard. No cabin was built but he would spend time in his trailer whenever he didn't want to go back to the Hyatt hotel in San Francisco where he was staying for the duration of the shoot.

VX in liquid form, as presumably shown in the film by the small balls containing the substance, does not take effect immediately. After absorption through the skin and/or mucous membranes, it takes approx 1 to 2 hours before visible nerve agent symptoms begin to show. However, if a person is exposed to the aerosol form of VX, effects are immediate. In either case, the symptoms of VX poisoning resemble more of a full-body seizure than a bubbling/melting of the skin. Atropine must only be injected into the heart when poisoning by the aerosolized version occurs. Otherwise, the atropine is injected into the thigh. Furthermore, Atropine is also poisonous to the human body when it's injected into the body before aerosolize exposure occurs, either case Atropine's main side effect weakens the human body to the point of incapacitation and would be in no fit state to diffuse a bomb or get up and run and wave flares as depicted in the movie.

Although the film was shot in the Super 35 process, the HDTV version (which uses the 2001 Criterion Collection remaster) Pans and Scans as if it were shot in Anamorphic Widescreen instead of properly framing it for Full Frame as most Super 35 films are. The 4:3 version that is found on the original VHS release is mostly open matte with some mild cropping.
