Wells is assumed to have had a degree of control over the project that was unprecedented for a screenwriter, and personally supervised nearly every aspect of the film. Posters and the main title bill the film as "H. G. Wells' THINGS TO COME", with "an Alexander Korda production" appearing in smaller type. In fact, Wells ultimately had no control over the finished product, with the result that many scenes, although shot, were either truncated or not included in the finished film. The standard version available today is just 92m 42s, although some prints are in circulation in the United States - where the film is in the Public Domain - that retain the additional scenes that constitute the original American release.
The film, written throughout 1934, is notable for predicting World War II, being only 16 months off by having it start on 23 December 1940, rather than 1 September 1939.
