Good limited location films:

There are some famous examples: resevoir dogs, killing zoe, rear window, the tenant, lifeboat


How about some others.

Here are some of mine:

Tape (linklater)

Pontypool

Breakfast Club (sort of limited)

Olenna

Carnage

Bug


Funny Games

Buneul's Discret Charm and Exterminating Angel

Arsenic and Old Lace

Evil Dead II
Cabin Fever
Baghead
The One I Love
Any number of haunted house films
