You'll never guess how they made that Wizard of Oz colour transition

The moment Dorothy emerges from her house after the tornado in MGM's The Wizard of Oz is one of the most memorable scenes in movie history, but have you ever wondered how it was made? Dorothy appears to step from a black-and-white world into a colour world, but this was 1939, when there was none of today's AI-powered trickery.

A video on TikTok has become a massive hit after dissecting the scene and breaking down how the effect was achieved. And it shows just how ingenious filmmakers had to be before the advent of CGI and deepfake technology, and how the results could be just as stunning for the audience.
