I was thinking that the movie could be about one of the people from the other planet, (Calamador) 20 year old NFP male. The first part of the movie being a comedy of errors, him trying to figure out basic details and etiquette of the world. (Clothing and housing and food and stuff.) Lots of bumping into walls and generalized sensotard moments. When he starts to figure that part out, he meets an SFP girl. (She’s helping him up off the ground or something.) They become friends and eventually fall in love. The plot could be that he can’t survive long in the physical world, and she can’t go back with him to the invisible world, so they are trying to figure something out.
Her: “We can’t be together, because you’re from Calamador”
Him: “I believe anything is possible.”
Lots of cheesy scenes of her showing him how to swim at sunset and such. But eventually she has some Earthly problems like paying bills or getting sick.
Him: “But in Calamador, the world has nothing so it can be turned into anything. Life can be what you’ve always wanted it to be!”
She throws a temper tantrum: ‘I’M SICK OF YOU AND YOUR WORLD!!!!”
They make out.
Make your own ending.
