When Grimm first enters the bank he tells everyone not to move. Then he charges towards a woman with a dog saying "What did I just say?". As he was walking, the dog owner was "hugging" the dog around the neck and no collar or tags could be seen. Immediately after that she is just holding the dog with the collar and tags resting on her hand.
When the bus is departing the bus stop sign only shows that the Q9 route stops there. Yet the route map that is below the bus stop sign is for the Q56 route.
During the end airplane sequence, an exterior shot is shown of the engine starting. The red-flagged safety pin for the main landing gear is clearly visible. This is normally removed during preflight unless the airplane is in maintenance. The airplane would not be cleared to fly with this in place.
Reflected in window of subway car during opening pan across the riders' faces.
In the opening scene, based on the 1 train arriving at 42nd St., Grimm gets off the subway at Times Square. Based on the surrounding scenery the bank is very clearly on Park Ave. Logically Grimm should have been getting off a train at the (much closer) Grand Central, rather than walking over half a mile crosstown in a very conspicuous costume.
