Doesn’t have to be one you think is true or even possible. Could be niche or mainstream. Mine is probably Mike Tyson threw that Jake Paul fight. I heavily believe Tyson did everything he could and is just old. Not to mention he’s fighting a roided up good athlete in his physical prime with a limited engagement strategy. I do like hearing people argue its all staged, understandable cope.
They later said the only finished animations were the ones in the trailer. Live action filming was done, but they had barely gotten started on the CG animation when the awful trailer dropped, so it was easy to change course and redesign Sonic for the rest of the film. Also, the film was delayed while they made changes, so it did cause a setback.
Although I would believe that somebody dropped that trailer to prove a point that no one would watch a Sonic movie with that abomination. After the outrage and public backlash, the point was proven and whomever greenlighted the original design backtracked and let the animators fix it.
