4. Cats (2019)

Though designed to be an entertaining musical with an all-star cast, this movie ended up becoming one of the most unintentional horrors, crossing directly into the uncanny valley. Its use of digital fur technology to blend human faces onto CGI cat bodies is physically repulsive on many levels. The characters seem to lack basic awareness of the space they occupy. Proportions and scale shift between scenes. The surreal imagery looks as if it emerged from the darkest depths of a shattered subconscious mind.

3. Buried (2010)

As an exercise in extreme claustrophobia, 'Buried' takes place completely within a single wooden coffin buried six feet under in Iraq. Shot entirely inside a wooden box, this film focuses on the struggle of Ryan Reynolds' character to survive.
