Sonic the Hedgehog had a slight alteration to the end credits on the Blu-ray release compared to the theatrical release.
[WARNING: SPOILER ALERT, YOU ALREADY KNOW WHAT I’M TALKING ABOUT IF YOU WATCHED THE MOVIE]
There’s no credit for Coleen O’Shaughnessey as the voice of Tails in the mid-credits scene in the theatrical release but she is credited on the Blu-ray release.
Makes sense that they would retroactively add a credit for Tails’ voice since it’s one of the most spoiled scenes in the movie, and probably one of the most spoiled mid-credits scenes in all of modern cinema.
