Windfall, also released as Dangerous Money, is a 1955 British second feature ('B')[1] comedy film directed by Henry Cass and starring Lionel Jeffries, Jack Watling and Gordon Jackson.

The lives of shop assistant Arthur Lee and his family are transformed when he finds £2,000 on top of a bus.

Arthur's daughter's dodgy boy friend steals the money, but lands in trouble when it's discovered to be counterfeit.

The acting is generally adequate, with hard work by Lionel Jeffries in the most substantial part.

Its humour, slightly satirical, and sentiment are down-to-earth, and Lionel Jeffries, immense in the lead, smoothly blends them into a warm and diverting whole.
