Deathline (1997)

Factual error: In one shot, the camera is on the platform at Tottenham Court Road station, and a sparkling new train rushes in. Wrong type of train - the one used is from the semiautomatic Victoria Line stock. I suppose London Transport must have been too ashamed of their Central and Northern line trains to have allowed them to be filmed.

Continuity mistake: The topless blonde assassin knocked out by Wayne appears dead a few scenes later over a puddle of her blood but with no visible wound. She is trying to get up when Marina appears to pick up a gun and taunt Wayne who's dealing with the other nude assassin, only to still be lying down a cut later. Marina could have shot her dead at this point, but doesn't and therefore the blonde's death makes no sense. The assassins' corpses are also lying in different positions than before.
