So what is Epic Mickey: Rebrushed about anyway? There might be some changes in the remake, but the original story centers on Mickey finding his way into a sorcerer's workshop (Yen Sid from Fantasia) after going through a looking glass. It's here that the mouse finds a magic paintbrush and accidentally wreaks havoc on a magical world filled with forgotten Disney characters. After getting sucked into this world, it's now Mickey's job to put things right and defeat a foe who's bent on getting in his way.
