Definitely MIRAGE, as BK noted, but first in that decade there was CHARADE.
Other than those, what would I personally identify as really Hitchcockian? I don't know. Could FRANTIC qualify?
I won't include Brian De Palma's blatant homages to Hitchcock, because, well, duh. And the mostly dumb remakes of things by other people only copy the general story line; they have no idea what made the original film a masterpiece.
