In a catastrophically polluted Earth, the technological city of ‘Ecoban’ is built but refugees affected by radioactivity are not welcome there. This Korean Sci- animation was made using both 2D and 3D images which were combined using the latest technology known as ‘Multimation’. At a cost of 12.6 billion KRW, Wonderful Days took 7 years to make and has the overwhelming visual effects possible. (MO Eun-young)
