That's My Man is a 1947 American drama film directed by Frank Borzage, written by Steve Fisher and Bradley King, and starring Don Ameche, Catherine McLeod, Roscoe Karns, John Ridgely, Kitty Irish and Joe Frisco.

[1][2][3] Joe Grange quits his job as a Los Angeles accountant and gambles all of his savings on a racehorse named Gallant Man, the longest of longshots.

But when she expects a child, even Joe's winning of a house does not make her trust his ways.

Joe is too busy playing poker to be there when son Richard is born, and he is suckered by horse trainer John Ramsey into betting $40,000 on a race, blowing it all.

When he hears Ronnie is entering Gallant Man in a $100,000 race at Hollywood Park, he tries to stop her before she loses everything.
