"There's no place like home" — The Wizard of Oz (1939)

More than any line in cinema history, Judy Garland's unassuming wish in The Wizard of Oz (1939) became a universal symbol of belonging, repeated annually on American television from 1956 to 1991. The line, drawn from L. Frank Baum's 1900 novel, transcends its simple sentiment: it has been referenced or reprised in over 300 films and TV episodes, making it the most quoted movie line by sheer volume. This far eclipses the cultural footprint of #10's "Go ahead, make my day," which appears in fewer than 60 subsequent works, despite ranking higher on the AFI list at #6 versus this quote's #23. Garland's delivery, culminating in the iconic click of her ruby slippers, anchors a story seen by more than 45 million viewers during its first network television airing in 1956.
