Visible crew/equipment: After Leslie Tiller is stabbed with the garden shears, when Nicholas chases after the hooded figure, just as he dives over a table with potted plants the blue crash mat is visible under the table. (Slow motion is not necessary.) (01:07:00)
Chosen answer: In the pub Danny demonstrates using a ketchup packet to simulate stabbing himself in the eye. Later in the film he returns Nicholas Angel's notebook, hiding a ketchup packet in it. He stabs the pocket with the notebook, causing the ketchup to leak and simulate blood.
