A short overview of special effects before the 30s

Before talking about special effects in the films of the 1930s and the 40s, it would be interesting to know where was exactly the development of FX techniques at the late 20s.

Actually, American film making flowered in the 1920s. Film makers began to branch out beyond the artistic and technical boundaries established by the pioneers of the previous decade, and relied increasingly on special effects. The first studio departments dedicated to the creation of special effects were created at this time. Either way, the term “special effects“ received its first screen credit in the 1926 Fox picture What Price Glory ?

The 1920s knew the beginning of the wide-sprayed use of small models in the film making industry (models, objects or locations that were too big, expensive or impractical to be filmed in any other way). At this time, Hollywood was the world’s leading film factory, but the special effects of German film makers, with their mechanical expertise, was technically far superior (particularly the ambitious and expensive productions directed by the German film maker Fritz Lang).

Thus, German films were a major influence on American film makers of the 1920s. The spectacular The Thief of Bagdad (1924) used opulent sets and the best effects Hollywood could buy in an attempt to compete with German films of the time. Moreover Ben Hur (1925) required the creation of a full-scale Circus Maximus and a fleet of seven huge Roman galleys on location in Italy. But a number of incidents — including the burning of the galleys (!) — combined with bad weather and Italian labour disputes, brought the production back to California. The film was completed rebuilt sets with significant use of miniatures.

When filmed from the correct angle, the combination of full-scale set and miniature is seamless (bottom). The foreground miniature film technique used is succinctly explained by the sketch below.

This technique (therefore often called “hanging miniatures“) will be frequently used in the 1930s and 40s film productions.
