The Wizard of Oz was released in 1939.

It was a standout for its use of Technicolor’s three-strip color process – using both black and white and colour.

Remember at the start of the Oscar-winning film it’s in black and white?

No?

OK, here’s a recap of the plot in case you need it.

We start with Dorothy, played by Hollywood star Judy Garland, and her little dog Toto living a “colourless” life in Kansas.

When a tornado rips through the state, Dorothy and Toto are swept up in their house and taken to Oz.
