My Wife's Family is a 1956 British comedy film directed by Gilbert Gunn and starring Ronald Shiner, Ted Ray, Greta Gynt, Diane Hart and Robertson Hare.

Jack Gay, a newlywed with a dominating mother-in-law attempts to surprise his wife Stella with a baby grand piano, but when she overhears him discussing it, she mistakes it for an illegitimate child, particularly with the arrival of his ex-girlfriend, the blonde and glamorous Gloria Marsh.

Ronald Shiner as Doc Knott gives a robust display of over-confidence, while Ted Ray successfully suggests the harassed Jack.

"[5] TV Guide wrote, "The third screen version of Fred Duprez's play proves once and for all there's no hope of reviving the dead... Overplayed without shame, but that doesn't help the ancient jokes any.

"[6] Sky Movies noted a "broad comedy, with Ronald Shiner and Ted Ray extracting the maximum number of laughs out of the mother-in-law-coming-to-stay situation.
