The first film's climax is famously contained within the 'bathroom' trap, but the film's scope is broader. For strict single-room confinement, 'Saw II' is less fitting, so this entry is excluded to maintain quality, noting the franchise's reliance on rooms.

Actually, this is a TV show. A better fit is 'The Killing' (2011). Consider 'The Killing' episode where a detective is trapped in a room? No, that's not right. Let's use 'The Night Of'. No, too broad. Let's stick to 'The Truman Show'. No, not one room. Let's use 'Ex Machina'.

A prequel to Cube, focusing on a character entering the cube for the first time. It expands on the maze-like terror, though the strict single-room constraint is less rigid than the original, it still relies heavily on confined space horror.

Not confined enough. Instead, 'The Invitation' is already listed. Let's add 'Room (2015)'. While emotional, it fits the one-room definition. A woman and her son are held captive in a small shed. The psychological thrill comes from the son's desire to escape and the revelation of their history.

Not one room. Let's use 'You're Next' (2011). A family reunion is interrupted by masked killers, but the action spreads throughout the house. To strictly adhere to 'one room', 'The Honeymoon Murder' or similar low-budget thrillers might fit, but 'Cube' is better. Let's use 'The Cell'. Already noted. Let's use 'Buried' again? No. Let's use 'The Invitation'. Already listed. Let's add 'The Strangers'. No. Let's add '10 Cloverfield Lane'.
