Filmed entirely in VR, using a camera within the virtual reality called VRCLens. It allowed Joe Hunting (the director) to "capture moments in a very organic and handheld style."
All of the people interviewed remain very active in their VR communities. Along with that, the director Joe Hunting posted on his Twitter account photos of the multiple countries and film festivals the movie was shown at, along with the main cast of the film and other of his friends he met in VR Chat. Toaster and DustBunny got to meet and have lived with each other for over 3 months at the time (confirmed by DustBunny's Twitter), and IsYourBoi and DragonHeart finally met each other in person too.
Scout and DylanP, the two space dogs, are actually a couple, and were in the same room when the documentary was filmed. They had to mute their microphones each time the other would speak, in order to not echo. They are the only characters in the film that were simultaneously next to each other IRL and in VR at the same time.
