Sonic the Hedgehog (Sony Pictures) (Susser and Robichaux's Version)

Sonic the Hedgehog is a planned live-action/animated crossover based on the Sega video game franchise of the same name that was announced in June 2014, and was originally going to be made by Columbia Pictures and Marza Animation Planet, as a lucrative joint venture.

Plot
Unknown, but probably would have far more faithful than the final product.

Why It Was Cancelled

 * 1) Director Jeff Fowler treated the original writers Susser and Robichaux in the film's production completely unnecessarily.
 * 2) Jeff Fowler came up with an arguably bad excuse saying "it didn't make sense to obviously bring in the Super Sonic thing just yet."

Results

 * It was confirmed that the movie would have no inspiration from the plot of the games at all, and instead would be a wholly original story, but still feature what the fans like about the character.
 * In February 2016, Sega delayed the film to 2018.
