House of Games movie review & film summary (1987)
Almost all of David Mamet's movies involve some kind of con game. Sometimes it is a literal con, as in "House of Games," where a character is deliberately deceived by fraudsters. Sometimes it is an inadvertent con, as in "Things Change," where an old shoeshine man is mistaken for the head of the Chicago mob. Sometimes it is a double con, as in "Glengarry Glen Ross," where real estate salesmen con customers while they are themselves being conned by the company they work for.
