'Ephemeral' was developed and written one month prior to production. Due to production restrictions of a previous project that was initially to be made, Writer/Director went back to the writing board and crafted a completely new story and new characters.
Writer/ Director Antonio Darwiche was the first person to cast actress Savannah Zapata, who plays 'Hailey Garland' in the movie. She was cast as the lead in the initial project prior to 'Ephemeral', but Antonio made sure she got a part in the new short that was about to be made in its place.
Actor Brian Gleason, who plays 'David Garland' was the third person to be cast for the role. He was found and attached to the project the night prior to day 1 of production.
