I can see it now...starring Shia LeBeouf!
I was going to suggest that the role of Chris go to Ben Stiller. But I like your casting better!
I dunno. Half of the time that efforts involving Sonic are subpar, at least some of the blame is due to Sega rushing things out the door too fast. I've heard that's a possible reason why
Sonic Boom really couldn't match its hype at E3 this year, because the higher-ups in charge of such decisions wanted a demo at the event, goddammit.
I can see this movie being enjoyable, even if there are elements are live action. I'm thinking that the story could take place in a CGI-generated otherworldly environment, like that of the Wachowski siblings' stab at
Speed Racer. You could have a human character like Sam Speed in
Sonic X (the police officer / Formula-1 racecar-driving guy), whose presence in the story would heighten the sense of tension because he approaches Sonic's capabilities and can be an actual threat. I'm not sure if Eggman should be played by an actual actor... He's coexisted around more conventional humans in his cartoonish form in certain games to varying degrees of cohesion, and I think something would be lost in dubbing Mike Pollock's voice over a real-life actor.
I know this is a broad statement for any adaptation, but I'm sure if the right writers were given adequate time to write a good script, I'm sure that they'd turn in something most people could enjoy. Speaking of the writers, just who the hell are these
Susser and
Robichaux guys anyways? According what I could find, they've mostly done short films and
are also obligated to write a live-action Jetsons movie. Why not ask Ian Flynn or some of his cronies at Archie to submit a draft for this? They clearly understand the Sonic franchise, have passion for it (at least that's my impression), and I think they've done some great work for the comic in the last couple of years. I think the recent
Worlds Collide special shows that they're entirely capable of writing an entertaining self-contained story.
