The Borrowers (1973)

The miniature Clock family, headed by parents Pod (Eddie Albert) and Homily (Tammy Grimes), live under the floorboards of an old English house. To sustain their living, the family must borrow common household items from the humans above. When a young boy (Dennis Larson) finds the family one day, he begins a friendship with Arrietty Clock (Karen Pearson), the young daughter. Unfortunately, not everybody wants the best for the wee family, and they are forced to flee to avoid being captured.
