Movies That Took Ages to Make

If Leni Riefenstahl knew the Second World War was fast approaching, would she have started this project back in 1934? Probably not, but after gaining influence and money through her close affiliation with Hitler and providing the German government with Nazi propaganda, the filmmaker mounted her own production studio in 1940, in the hopes of completing her movie. However, her plan was derailed by the war; the footage was confiscated by French authorities in 1944, and only returned to her several years later. The result was 20 years of on-and-off efforts to produce a pretty bad movie.
