“Not only did the footage show the CG-animated Sonic in action and interacting with humans, it also revealed Jim Carrey as Doctor Robotnik -- yes, the movie seems to mostly refer to him as that rather than Doctor Eggman -- who doesn’t look as much like his game/cartoon counterpart as fans might expect. He's not particularly egg-shaped and he isn't bald (at least not in most of the footage shown, more on that below).
There were two pieces of footage shown, the first devoted mostly to Sonic and the other to Robotnik, with the latter sizzle reel cut as if it were Robotnik’s movie and not Sonic’s. The Sonic footage opened on a country road as James Marsden’s small town cop, Tom Wachowski, sits parked, his radar gun waiting to catch speeders. And that’s when -- whoosh! -- a blue streak zooms past. Tom can’t believe his eyes.
We see Sonic’s POV as he races down the road and through the woods. We hear him say “Gotta go fast” as Coolio’s “Gangsta’s Paradise” plays. Tom finally catches Sonic as the latter is hiding inside a shed. Sonic just says, “Uhhh, meow?”
We see Tom driving with Sonic in the passenger seat of Tom’s vehicle as Sonic explains that he’s here to save our planet. There are shots of futuristic (presumably alien) ships in the sky and then Sonic confronting other hovering weapons while making a Fitbit wisecrack.
Tom and his wife (played by Tika Sumpter) have to smuggle Sonic into an office building, hiding him in Tom’s gym bag. But Sonic won’t stop talking, complaining that the bag smells like Right Guard deodorant and an old ham sandwich. The movement inside the bag and Sonic’s chatter get the attention of two bystanders as the Wachowskis wait for an elevator. They think they have stuffed their child inside the bag. Tom advises them that it’s not their child but there is *a* child in it.
The footage ended with one quick shot of Jim Carrey as Robotnik. He looks like, well, Jim Carrey with a big, waxed handlebar mustache. He’s not bald, and is dressed in all black (trenchcoat, boots).“
