In Revenge of the Sith, Anakin, Obi-Wan, and Palpatine were trapped by a ray shield on the Separatist ship the Invisible Hand:
60 INT. BRIDGE-TRADE FEDERATION CRUISER
BODYGUARD: General, we found the Jedi. They're in hallway 328.
GENERAL GRIEVOUS: Activate ray shields.
61 INT. HALLWAY-TRADE FEDERATION CRUISER
They run down the hallway. Suddenly, ray shields drop around them, putting them in an electronic box in the middle of the hallway.
ANAKIN: Ray shields!
OBI-WAN takes a deep breath to express his total disappointment.
OBI-WAN: Wait a minute, how'd this happen! We're smarter than this.
It seems as if this shield was purposefully built to trap individuals (since the projected shield is an "electronic box"):
But why would the ship's designers put a ray shield in the middle of a random, unimportant hallway 328? Was the shield actually built to trap individuals or for something else?
If I had to guess, I would think that a ray shield in the middle of a ship's hallway might be useful for defending the ship against a boarding party...but this shield doesn't block the entire hallway, it just blocks the middle of it. Or can the shield generator project a planar shield so that it forms a wall? But even then, why not just use a blast door like the ones used on the Death Star?
Are there any other ships in the Star Wars universe that used ray shields in their hallways and, if so, what did they use them for?
- Were they really meant to trap individuals?
- Were they used to help defend the ship against a boarding party?
- Were they just crappy plot devices used to force the Jedi to introduce us to General Grievous, poke fun at the dumb Jedi for getting trapped, and break plot consistency?
- Were they used for something else?
