Easy Money is a 1948 British satirical film directed by Bernard Knowles and starring Greta Gynt, Dennis Price and Jack Warner.
When matters reach a point where they begin wishing that they had never won the money, the youngest daughter announces that in fact she forgot to post their entry, and they all regain their previously happy lives.
But then it is discovered that it was a previous entry she had forgotten to post and the winning coupon was mailed, and they decide that they have learned a lesson and resolve not to let the money ruin their happiness.
He finds the prospect of having to tell his employer that he is resigning too daunting, so he plots with a friend that he will fake illness as a way of leaving, but the deceit proves so taxing that he suffers a heart attack.
The third is a crime caper involving a part-time coupon checker and his nightclub singer girlfriend who devise a scheme to embezzle the winning pot.
