Charade is one of my favorite Cary Grant movies even though it's late in his career. A homage to Hitchcock, it combines everything you mention with a fine score by Henry Mancini, the theme song one of my favorites from his work. Hepburn and Grant mesh amazingly well; she was, in a way, one of the major bridges between old Hollywood of Bogart, Cooper, Grant, Peck, Holden, Astaire, Fonda, Lancaster and the newer Hollywood of Alan Arkin, George Peppard, Peter O'Toole, Anthony Perkins, James Garner, Connery that arose in the 1960s. Given how her career only began in the early 1950s, it's surprising she got to work with so many stars from the '30s and 40's.

Session 9 (2001) -- A crew wins the bid to clean out Danvers State Mental Institution, a huge, rambling building from the 1800s closed fifteen years earlier after a scandal. Each of the cleaners has issues and their issues magnify while in the building, something stemming from the murders committed by one of the inmates seeming to infest the Institution and affect them. Starring David Caruso, Peter Mullan, with Josh Lucas shortly before he became a leading man, this is one of the better supernatural thrillers I've watched lately. Funny that, roughly, between 1999 and 2001 there were so many solid, effective ghost/horror movies like The Others, The Blair Witch Project, and The Sixth Sense that relied more on misdirection and implication than on special effects.
