A prevailing question in Amazon Studios’ first original animated series Undone is whether Alma Winograd-Diaz (Rosa Salazar) has the ability to travel through space and time to prevent the untimely death of her father Jacob (Bob Odenkirk) or if she is suffering from mental illness. In order to seamlessly integrate the fractures in reality, creators Kate Purdy and Raphael Bob-Waksberg (BoJack Horseman) collaborated with director Hisko Hulsing (Montage of Heck) to produce a hybrid style that combines live-action performances, oil painting backgrounds, rotoscoped characters and 3D animation.
