Heist Movie Cliches

[Qwerty]

Making a Minecraft map about stealing emeralds, it plays in the style of a standard heist movie. As such I'm trying to get as many heist movie cliches as possible, or at least the favorites, to incorporate into the map. As such, I'm asking you guys to list as many heist movie cliches you can, specifically those related to security systems and bypassing them. I tried Google, but all of those are more about the movies and less about the security.

So far, we have:

• Valuable gemstone rests on a plate, have to replace it with something before taking gem or alarm goes off.
  
• Dodging unrealistic glowing red lasers or the alarm goes off.
  
• Blast or cut into the top of the main vault, then rappel down.
  
• Ventilation shafts. All sorts of ventilation shafts.
  
• Unrealistically easily hacking into a central computer system that controls EVERYTHING.
  
• Central guard room with security cameras that let them monitor people in areas. Usually shut down with above system.

Fumbling guards who destroy stuff so that would be that monster who destroys block in a different skin in mine craft? I don't know the names of stuff sorry.

The guards in this case are other players, and no block destruction in the map. Too much redstone for that.
