10 Movie Secrets Never Meant To Be Found

1. Recycled Backgrounds - Transformers: The Movie

In the years before home video popularity surged, it was extremely common for studios to recycle animations from previous films for their new releases, as is almost embarrassingly obvious nowadays in a number of classic Disney films.

But a slightly less obvious example comes from 1986's Transformers: The Movie, produced by the legendary Japanese outfit Toei Animation.

The sequence when Unicron devours the planet Lithone features a shot of Unicron's innards munching away, and the bulk of the visual is lifted directly from Fist of the North Star, another film released by Toei a few months earlier.

In addition to being a quick way to save some money, Toei likely assumed nobody would ever put two and two together. But of course, modern home video tech makes it incredibly easy to spot the similarities when they're viewed side-by-side as above.
