To Catch a Thief (1955, dir. Alfred Hitchcock)

A former jewel thief comes out of retirement when his Riviera lifestyle is threatened by a pretender. Glossy and deft romantic comedy with a few knowing touches, with a lighter touch than typical from its director, some still-impressive optical effects sequences aside. Happy to serve the daft conceit, the cast and crew relax and enjoy themselves.

North by Northwest (1957, dir. Alfred Hitchcock)

A New York advertising executive is forced to go on the run. Sparkling mistaken-identity comedy-thriller, with both director and star at the height of their powers. Effortlessly entertaining, and supremely modernist in its design.
