I'm doing research for an Imagineer series I'm launching and found something exciting. Chris Beatty, the Portfolio Executive Creative Director on all of the WDW projects right now, is a big fan of Hades:
"During the roundtable discussion Beatty explained the process of designing a new attraction with a focus on the Seven Dwarfs Mine Train, the close working relationship WDI shares with Feature Animation to help accurately portraying characters, and for good measure, his favorite Disney character. Spoiler: It’s Hades."
If Hades has a big role in Villains Land, well, this explains it.
