It's the Old Army Game is a 1926 American silent comedy film starring W. C. Fields and Louise Brooks. The "army game" is the shell game, a con-trick which WC Fields observes being played. "It's the old army game" he says, sagely. The film was directed by A. Edward Sutherland, billed as Eddie Sutherland, and co-stars Sutherland's aunt, the stage actress Blanche Ring in one of her few silent film appearances. The film is based on the revue The Comic Supplement by Joseph P. McEvoy and Fields, and included several skits from Fields' stage plays.
It's the Old Army Game was the fourth film that Louise Brooks appeared in. Sutherland and Brooks married in June 1926, and divorced in June 1928.
