NEW Wonka movie just got announced, set for release next year, and the blueberry scene is integral to the story:
Charlie vs. the Chocolate Factory tells a new story, set years after Wonka's infamous Golden Ticket contest. Indeed, Wonka has just returned to his factory following a stint behind bars (for turning a child into a blueberry, as seen in the original Charlie and the Chocolate factory book and film).
"Having served his time, Wonka returns to his factory determined to add a little sweetness to a bitter world," reads an official blurb. "But one thing stands in his way: teenager Charlie Paley and his friends. Facing eviction, this next generation of 'rotten' kids plot to break into the factory, nab a priceless Wonka Bar, and save their homes. But like many before them who enter the fantastical world of the factory, these kids are in for a bit more than they can chew..."
