Don't Tell Everything is a 1921 American silent drama film directed by Sam Wood and starring Gloria Swanson and Wallace Reid.

Wood apparently created this film in part from outtakes left over from Cecil DeMille's The Affairs of Anatol (1921).

[1] As described in a film magazine,[3] Cullen Dale (Reid) becomes engaged to Marian Westover (Swanson), and when explaining various photographs showing him intimately juxtaposed between divers young women, spreads a network of falsehoods which promise to involve him in subsequent difficulty.

Learning of Cullen's engagement, she courts his company so consistently that the piqued Marian precipitates a secret marriage.

Here Jessica's love-making becomes obvious and the arrival of wife Marian and their mutual friend Harvey Gilroy (Dexter) finds Cullen ready to patch up their differences.
