When Eric Dane goes to shoot Steven Ivory in the leg, he first pulls the trigger but the gun doesn't fire. On the second attempt, it works.
When Falco is hit by the fire extinguisher, he drops to the ground unconscious but his eyes are open until an awkward second passes and he realizes to quickly close them.
Ritter is horrified when Falco kills Jarvis, the security guard, and even complains that he's working with psychopaths. A few scenes later, Ritter is suddenly acting like a psycho too as he is perfectly fine with killing people.
