One animator worked on this? WOW!

This is one complex scene to animate. 12 characters doing 12 different things all at the same time. Cheers to whoever the key animator was.

Wow, I know I'd fuck up and loose track of at least one of the Characters if I did this, really complex scene, you can go through it a dozen times just looking at the individual Characters.

must've been a pretty thick pile of cels on the filming stand

Ok... This is freaking amazing! All of them feel so damn alive it is nuts, this might have become one of my favorite character acting cuts of all time, being able to pull something like this takes unbelievable amount of skill and precision, kudos to Yamazaki if he is the one who did this.

I honestly commend all the staff for this Urusei Yatsura film, I really recommend it, it was so much fun :)
