穆里尔·博克斯，Muriel Box (22 September 1905 – 18 May 1991) was an English screenwriter and director. She pursued her favourite subject – the female experience – in a number of films, including Street Corner (1953) about women police officers, Somerset Maugham's The Beachcomber (1954), with Donald Sinden and Glynis Johns as a resourceful missionary, again working with Donald Sinden on Eyewitness (1956) and a series of comedies about the battle of the sexes, including The Passionate Stranger (1957), The Truth About Women (1958) and her final film, Rattle of a Simple Man (1964). Box often experienced prejudice in a male-dominated industry, especially hurtful when perpetrated by another female. In 1950, Jean Simmons had her replaced on So Long at the Fair, and Kay Kendall unsuccessfully attempted to do the same with Simon and Laura (1955). Many producers questioned her competence to direct large-scale feature films, and while the press was quick to note her position as one of very few women directors in the British film industry, their tone tended to be condescending rather than filled with praise.
