||Sound (sound effects & music; no narration), 21 min. In May 1940, a massive Luftwaffe raid devastated much of Rotterdam and killed over 25,000 of its citizens. Twelve years later, in 1952, Rotterdam's city fathers sought to commemorate that tragedy and, at the same time, to celebrate their city's reconstruction with American aid. The film served as centerpiece of those ceremonies. The title, HOUEN ZO!, is a crane operator's term meaning "steady" or "steady on". Without words, but keyed to the rhythm of church carillons and street hurdy-gurdies, a series of vertical wipes replace ruined old buildings with new ones, one by one. Produced and directed by Herman van der Horst, Haarlem, and made at Cinetone Studios, Amsterdam. Remarkable for its dramatic camera work, sound effects and music, HOUEN ZO! won first prize at the Cannes Film Festival, 1952. Van der Horst's documentary SHOOT THE NETS, sponsored by ECA Netherlands, had already won that coveted prize in 1951. NB: The Dutch government maintains that it holds the rights and currently charges a fee for the use of this film.
