Sometimes 15 seconds is all it takes.
Months ago while channel surfing I caught a short trailer for an upcoming TV anime series, nothing but a short 15 sec blurb; 3 characters in a chase scene through some mundane Tokyo neighborhood. It was so short I didn’t even manage to catch the title, but the animation was jaw-dropping; unmistakably feature film quality.
Next day at work the animation folks were already talking about the same trailer I saw. It turned out our neighbour from across the street, Madhouse ( the folks who gave you Tokyo Godfathers, Paprika ), has a new work up their sleeves – Denno Coil. （電脳コイル）
