Midnight Lace (1960)

Plot:  In London, a wealthy American wife is being stalked and threatened - but by who?
Stars:  Doris Day, Rex Harrison, Myrna Loy, John Gavin

Alternate title:  How to be terrified in London on $1000 a day.  No one does hysteria/fright better than Doris Day! And she never looked better or was better dressed.  Lending fine support are Rex Harrison and Myrna Loy (who steals every scene). Supposedly, Day was worn down by all the negative emotion and refused to make another serious movie.  I'm not a fan of "women in danger" movies - but this is a fun little thriller (a sorta 2nd rate Hitchcock) with good production values.
