According to an article in the 16th October 1988 edition of 'The New York Times', veteran actor Don Ameche was originally cast in a minor role as one of the Dons in the movie. However, after a meeting with lead actor Joe Mantegna and writer-director David Mamet, Mamet decided to cast Ameche in the other lead role of Gino.
'Things Change' (1988) was writer-director David Mamet's follow-up movie to his directorial debut 'House of Games' (1987). Both pictures featured many of the same cast and crew totaling to around about fifty common personnel between the two productions. This included such actors as Joe Mantegna, William H. Macy, J. T. Walsh, Ricky Jay, Jack Wallace, Mike Nussbaum, and Steven Goldstein.
The film reunites many actors from the main cast of the 1984 play version of "Glengarry Glen Ross", also written by David Mamet: Joe Mantegna, Robert Prosky, J.T. Walsh and Mike Nussbaum.
