From The Verge:
In an interview with Complex, the film's director, Jacob Gentry, says that the short is based on a story written by Danger Mouse and inspired by sci-fi imagery sent to him by Mercer. "James Mercer was sending me images of Barbarella and Logan’s Run, that sort of late ‘60s/early ‘70s science fiction," Gentry said. "The same way we mixed all those visual styles is the same way Broken Bells mixed all the musical styles from every era to make something unique. It has an otherworldly feel." This is Broken Bells second time collaborating with Gentry — in 2010, they teamed up with Christina Hendricks of Mad Men for another sci-fi video, though it was only for a single song.
After the Disco is being released in installments, with the second part debuting last Thursday. Its creators aren't saying how many parts will be released in total, but with the second short's cliffhanger ending, it appears there's still more to come.
