According to Deadline, Jeff Fowler's forthcoming Sonic The Hedgehog movie is in the process of landing quite the casting coup: none other than Jim Carrey (most recently seen behaving like a real asshole in the Netflix documentary Jim & Andy: The Great Beyond) is currently in negotiations to star in the film as the evil Dr. Robotnik.
Fowler's film will feature a combination of live-action footage and CGI, and it's currently unknown whether Carrey will be voicing a computer-generated version of Robotnik or appearing as the character underneath a mountain of practical effects (and an outrageously large mustache).
For those unfamiliar with Sonic The Hedgehog mythology, Dr. Robotnik ("Dr. Eggman", if ya nasty) is an egg-shaped mad scientist dead-set on world domination. Wikipedia tells me that Robotnik's ultimate goal is to create an "Eggman Empire", a piece of information I won't be researching any further, because a) it's after 5PM on a Friday and b) I find the phrase "Eggman Empire" inexplicably upsetting. To dive any deeper into such mysteries is to court madness.
Anyhoo, Sonic The Hedgehog is currently finalizing its cast, gearing up for a production that should put the film in theaters on November 15th, 2019. Stay tuned for more on this one as it becomes available, and be safe out there.
