Die Hard with a Vengeance1995

[One of the guards has been trapped by Simon's men in his office and doesn't see Katya opening the door into the room. He manages to contact the front desk, not knowing that the front desk guard has been replaced by one of Simon's men]

Mischa:
Front desk.

Federal Reserve Guard #2:
Yes, call the police! Get your ass down here right now! I'm under attack!

Mischa:
Hey, just relax mate! Maybe you'll live through this!

[The guard, not trusting Mischa, grabs a shotgun and starts firing towards the door behind which Simon and his men are standing, calmly waiting. As he fires with no success, he fails to see Katya pull out a long curved knife, and she slashes it through his neck. As he begins to fall, she slashes a second time through his neck, spins around, and stabs him in the chest. As he doubles over, she stabs him in the back. Before she can stab the guy any more, Simon grabs her, twists her hand, and pins her against the wall, restraining her. He glares disapprovingly at her]

Simon Gruber:
I think he's dead, my dear.
