WILLISVISION INDEPENDENT FILM PRODUCTIONS OF COLORADO strives to promote the scenic cinema-photography of the state while only utilizing Colorado talent in front of and behind the camera. We offer a wide range of entertainment from music videos, dramatic films, or documentaries to Christmas and children-friendly programming, but we specialize in horror, sci-fi / fantasy, and fan films. Founded in 1985 by Colorado Filmmaker, Ben Willis, we've been fortunate enough to retain the same core staff over the decades, and have always been based out of Colorado Springs, Colorado.
There's also a Gravity Falls crossover in one of the episodes, where they are running through different portals to different worlds/universes. It's based of how in one of the episodes of GF, Stanley Pines attempts to create a portal to save his bro Stanford, and the portal sucks in some items. These same items are then seen in that episode of Rick and Morty, coming out from one of the portals Rick creates. The Simpsons couch gag one also has a futurama reference, with a vending machine from the show appearing when Morty goes to the alien world with the Simpsons' DNA. Also there's some references to Rick and Morty in Family Guy, notably the one where Stewie and Brian are travelling the multiverse, and Stewie has the same portal gun Rick has, and claims he got it off Rick and Morty (not specifies how, but probably not by force considering that Rick is way more powerful than he is).
I find it so cool that in this reality, I got to see these crossovers. the thing about Rick and humans, some of us have the ability to go to different realities just before we die even if it’s not our own control.
