Continuity mistake: Minnie gives her the necklace with the tannis root inside and Rosemary holds the chain between her thumb and first two fingers. In the next shot the chain is draped over her fingers. (00:32:15)

Continuity mistake: About 15 minutes in, Yaphet Koto and another man are in an elevator; there are hostages on the floor. Yaphet pulls a glove onto his left hand, but, in the next shot of him, he again pulls a glove onto his left hand, and then yet again he pulls a glove onto his left hand. The same hand three times.
Continuity mistake: When the sub surfaces at Zebra it is shown running up a tower. When we next switch to a close-up there is no tower and it is running up an antenna.
