The 33rd installment of โThe Simpsonsโ annual ‘Treehouse of Horror’ series was an ambitious one. Animation director Rob Oliver managed to bring three ghostly classics into the Simpsonverse, turning โWestworld,โ โThe Babadookโ and โDeath Noteโ into Simpsonworld, the Pookadook and Death Tome. โIt was taxing,โ Oliver said, but the work paid off โ the episode earned an Emmy nomination, making it the fourth Treehouse special to be nominated for a Primetime Emmy Award.
For Variety‘s “Making a Scene,” presented by HBO, Oliver and โSimpsons’s” consulting producer David Silverman broke down their process of creating this year’s special. “I was extremely nervous. People had wanted it for so long that it could have easily been a swing and a miss,โ Oliver said.
Creating โSimpsonsโ episode โDeath Noteโ style, Oliver and his team hired a Korean animation studio that worked on the original 2006 โDeath Noteโ to animate the entire Death Tome segment. โWe would have botched it,โ Oliver said. โSo, Iโm glad they took it from us.โ The segment reimagined all characters from Marge to Jailbird.
For the spoof of HBOโs โWestworld,โ the team perused the vast library of โSimpsonsโ lore and aggregated a huge number of iconic references all throughout Simpsonworld. Starting with the monorail, Oliver and Silverman took from Season 4โs โMarge vs. the Monorailโ episode. To make it look exactly like the original, the animation team traced over scenes from the orginal footage and then matched all the old and new colors by filtering them together. In addition, the team had to work around the difference in aspect ratios, which have changed from the boxier 4:3 to the wider 16:9 format. They managed to hide numerous other โfan nuggets” in the foreground and background of the segment, from the classic Canyonero jingle to Homer skipping through the Land of Chocolate.
When it comes to making an installment of ‘Treehouse of Horror,’ the creation process is much different than any regular โSimpsonsโ episode. Oliver explained that from script to air, these Halloween specials take about a year to create, compared to a normal episode which takes about nine months. While not quite as long as making a feature film, this year-long process gives animators and producers a chance to test their strengths.
โYou learn to be a little bit more nimble and I think I learned how to follow my instincts better,โ said Silverman.
As a yearly feat, thereโs little to no downtime from making one special to the next, which means Oliver had only a smidge of time to appreciate his teamโs work on ‘Treehouse of Horror XXXIII.’ He said, โThe day after this nominated Halloween episode aired, I started working on next yearโs Halloween episode.โ
