Derby Day (U.S. title: Four Against Fate) is a 1952 British drama film directed by Herbert Wilcox and starring Anna Neagle, Michael Wilding, Googie Withers, John McCallum, Peter Graves, Suzanne Cloutier and Gordon Harker.

Lady Helen Forbes, a recently widowed aristocrat, is planning to make the journey in spite of the disapproval of her social set who consider it unseemly for her to go while still in mourning.

As part of a charity raffle, dissolute film star Gerald Berkeley must reluctantly escort a wealthy grand dame to Epsom, although when the woman falls and injures her leg, her crafty housekeeper arranges for the young French Canadian maid to go in her place.

While waiting for the race to start, Lady Forbes and David Scott meet up again, and find themselves sharing confidences, as they were both bereaved by the same air crash.

The upper classes, represented by Anna Neagle and Michael Wilding – who contrive to look as though they were posing for an advertisement in a glossy magazine – suffer bravely but woodenly over their champagne.

The British class system was firmly rooted and unassailable in the early 1950s, and director Herbert Wilcox nicely milks its rituals and nuances at a great cultural event.
