The story of the making of The Nun's Story (1959) would, in itself, make a great book or documentary. It's extraordinary that this dramatic tale, tackling the very controversial subject of a nun leaving the order, has been nearly forgotten - even more so when one considers the director (Fred Zinnemann), the star (Audrey Hepburn) and the phenomenal reviews and box-office receipts. By the end of its initial play dates, the picture had become the most successful movie Warner Brothers ever made, with grosses surpassing the $7 million mark!
The Nun's Story was to close on a Sunday night, and The Tingler was going to open on Monday. We got in a huge spend the day wiring the vibrators to the seats. But that night, just at the most tragic moment of The Nun's Story, somebody touched the mastertch and the seats began vibrating in wave after wave. There was absolute pandemonium!" （）
