The animation in “The Simpsons: The Good, the Bad, and the Loki” is uncannily close to the appearance of the live-action “Loki” series, and it was allegedly a “true nail biter” to make — especially the last post-credit scene set at the TVA. In an interview with Variety, executive producer Al Jean discussed the crossover short, revealing that the crew barely had a week to construct the final post-credits scene. ” ‘Oh, we’ve got to do something with the series now that it’s on,’ [producer] Jim Brooks remarked, ‘because [‘The Good, the Bart, and the Loki’] is coming out on July 7th.’ So just the first episode was used in the [final post-credits sequence]. I hadn’t seen it before.
He went on to say that the final minute or two of “The Good, the Bart, and the Loki” was written, recorded, and animated in only one week. “Dawnn Lewis was recorded as the Judge. That’s how quickly David Silverman turned things around “Jean said. Anyone who has seen “The Good, the Bart, and the Loki” understands how well the animation team captured the TVA aesthetic. There are currently no plans for any Marvel-“Simpsons” crossovers, but we would love to see these two iconic realms collide once more. IMDB
