Continuity mistake: When Abby is finished washing the dishes, she tosses the towel she was using and it lands on top of a red can. An immediate close-up of the towel on top of the can proves this (0:25:29). A second later, the picture zooms out again to show her bending over from exhaustion (0:25:30). The towel is no longer on the can, but behind it against the wall. Abby follows the shop owner into a room adjacent to the kitchen and when they come back, the towel is once again on top of the can (0:25:55), but most of it is inside the can this time. It's obvious that neither her nor the shop owner has touched the towel and no one else is in the shop. (00:25:25)
Revealing mistake: In the opening scene, when Van Damme kicks an opponent onto the boot of a London Taxi Cab, you can see the dent from previous takes.
