Each second of "Undone" consists of twelve hand-drawn, rotoscoped frames.
One of the big misconceptions of rotoscoping is that all of the animation is done through software with the push of a magic button. In fact, rotoscoping is a very lengthy process that involves the physical art of drawing over live-action footage, one frame at a time.
While rotoscope animation has been used in TV before, "Undone" marks the very first time the technique has been used for an entire series.
Before her starring roles in film and TV, Rosa Salazar (Alma) had been pursuing a comedy career as a stand-up comedian while making shorts for the website, College Humor.
Series creator Kate Purdy has said that unique visual style of "Undone" was inspired in part by the animated sequences that Dutch artist Hisko Hulsing created for the film, "Kurt Cobain: Montage of Heck" (2015).
