The great director Alfred Hitchcock is known as the master of suspense, but many of his movies also featured marriages as part of the plot.
Mr and Mrs. Smith (1941): This is Hitchcock's only screwball comedy. It's about the complications that arise when a couple (Robert Montgomery and Carole Lombard) finds out their marriage isn't valid.
Rebecca (1940): A socially awkward newlywed (Joan Fontaine) must deal with the lingering presence of her aristocratic husband's first wife in this adaptation of Daphne du Maurier's novel.
Rear Window (1954): A photographer (James Stewart) and his girlfriend (Grace Kelly) become amateur sleuths after they seem to witness a neighbor (Raymond Burr) killing his bedridden wife.
Suspicion (1941): A shy young woman (Fontaine) begins to suspect that her husband (Cary Grant) is trying to kill her.
The Man Who Knew Too Much (1956): An American couple (Stewart and Doris Day) become enmeshed in an assassination plot while vacationing in North Africa.
