Tom at the Farm (2014)

Xavier Dolan's Hitchcock-flavored thriller sits in a standard 1.85:1 frame until the farm starts to close in. At key moments the frame itself tightens around the characters, constricting into a thin strip of widescreen, so you feel the situation physically narrowing. It works as a rehearsal for the far bolder gamble Dolan took a year later in Mommy, and it's the better choice if you want the technique inside a taut, unsettling genre movie rather than a family drama.
