easy
Directed by Celine Sciamma
Water Lilies · Tomboy · Girlhood · Portrait of a Lady on Fire
medium
Invisible characters
The Invisible Man · Hollow Man · Harvey · Memoirs of an Invisible Man
Every story here depends on someone the eye cannot hold onto. Sometimes that invisibility is scientific, sometimes comic, sometimes imaginary, but the absence is what steers the scene.
hard
A dead partner still shapes the present
Rebecca · Solaris · Birth · Truly Madly Deeply
These films all revolve around a relationship that should be over but refuses to stay past tense. The dead partner becomes a pressure system that keeps reorganizing the lives of the living.
tricky
Houses act like characters
House · Burnt Offerings · The Others · Crimson Peak
The buildings in these films do more than provide a setting. They impose moods, temptations, rules, and history so strongly that the house starts to feel like another performer in the cast.
