Vegemite story to become a movie

The story of Vegemite is about to be turned into a movie!

A book on the life of it's creator Jamie Callister has been written by his grandson, who has sold the movie rights. Mr Callister was a chemist, who lived through the Depression and both world wars.

Here's the history of Vegemite as edited in Wikipedia

In 1919, prior to the introduction of Vegemite, the Sanitarium Health Food Company in New Zealand began manufacturing and shipping to Australia a version of Vegemite's biggest competitor, Marmite. Vegemite was invented in 1922[3] by food technologist Cyril P. Callister when, following the disruption of British Marmite imports after World War I, his employer, the Australian company Fred Walker & Co., gave him the task of developing a spread from the used yeast being dumped by breweries. Callister had been hired by the chairman Fred Walker.[4] Vegemite was registered as a trademark in Australia that same year. Callister used autolysis to break down the yeast cells from waste obtained from the Carlton & United brewery. Concentrating the clear liquid extract and blending with salt and celery and onion extracts[5] formed a sticky black paste.
