Early previsualization work from the Sonic the Hedgehog movie surfaces

Some interesting test footage from the Sonic the Hedgehog movie has just popped up on the internet today. This is previsualization work, which is the process in pre-production of visually mapping out scenes in a movie before principal photography. This comes from long before the redesign of Sonic was announced, and is meant as way for those involved with the film to visualize what scenes might look like.
