Said O'Reilly to McNab is a 1937 British comedy film directed by William Beaudine and starring Will Mahoney, Will Fyffe and Ellis Drake.

[3] American confidence trickster Timothy O'Reilly has to flee New York with the law after him for his dubious business activities.

O'Reilly finds Terence is in love with the daughter of Malcolm McNab, a tight-fisted local businessman.

The two engage in a certain amount of rivalry while O'Reilly tries to find a way to refresh his financial fortune and get McNab's permission for their children to marry.

These include a game of golf at which both try to cheat and a miracle new dieting pill which is in fact just a caramel sweet.
