I had quite a nice time animating on this film, now that you mention it. Especially the second half of production was pretty enjoyable for me.
I'm responsible for all the animation except the single black and white shot for context, all spectators in the arena, and the pedestrians on the sidewalks in the segway chase shot. Music by Dann Beeson
Ridiculous editing is more fun than serious editing. I suspect we won't be making another Ice Age so I'm glad I got to work on the former flagship franchise that started it all for Blue Sky Studios. A reel breakdown identifying what I did not animate is in the video's description.
I hope you enjoyed watching this film as much as I had working on it. Which was a whole bunch! Here we have my favorite of the shots I animated for it.
