Because of the intricate rotoscoping and animation process, the productions teams of "Undone" could only animate up to three minutes of footage per week. The entire series took close to a year to complete.
The rotoscoping process used on "Undone" was incredibly detailed-to the point the animators were counting and drawing over individual eyelashes.
The entire series contains roughly 130,000 hand-drawn frames of video.
Animator Max Fleisher developed the original rotoscoping process in 1914.
About fifty thousand hours of individual rotoscoping work went into completing the character animation for series.
