I remember a scene where there was a man or a woman that was practicing something like defuse a bomb or some other tricky task in preparation of doing it in real life and he/she keep mistaking and someone keep saying that he/she was doing wrong..I remember a line something like “you keep killing us” or “you are dead again” when he/she err.
I recall seeing something recently with the same lines, though I have seen a lot of films lately. Possibly one of the Christian Bale Batman movies?
I’m pretty sure it wasn’t batman but thanks for the hint! 🙂
