Walk Don't Run

Cary Grant arrives in Tokyo early during Olympic week. With no hotel rooms anywhere, he pulls a card from the embassy bulletin board and talks his way into Samantha Eggar's flat. Later finding Jim Hutton, an architecture student and olympic athlete (who always avoids any identification of his event) who also has no room, he sublets his part of her apartment to Hutton and then tries to play match maker to the two of them.
