In 'Once upon a time,' ('Yeki Bood Yeki Nabood', 2000), a magical letter transports two men, Fahrad and Iraj, to a small house in the middle of the countryside - and into a world that's filled with cute talking animals.The men are happy to go along with it, but when the animals follow them back to the city, there are much bigger problems to solve. A delightful film for young children.
