A Very Unlucky Leprechaun(1998)

Luck can change in the twinkle of an eye.

Nine year old Molly and her father move to Ireland into a house they've inherited, nicknamed "Misfortune Manor". It brings bad luck to anyone who lives in it, and Molly and her father soon fall victim to the curse: they will lose their new found home unless they can pay the taxes they owe on it. Lucky the Leprechaun is on hand to help Molly break the curse and help with pots of gold.
