Box Office Bomb: The film proceeded to tank big-time on its opening weekend, and is now officially one of the biggest box office bombs ever. It scored the 12th worst opening for any film opening in 3,000+ theaters ($6 million) and suffered a net loss of over $110 million due to its $150 million budget and grossing only $39 million worldwide even with 3D grosses. Disney shut down Image Movers shortly before it was released.
Dawson Casting: Played straight and averted at the same time for the same character. Seth Green, who does the motion capture for Milo, was supposed to voice the character as well. However, it seems his attempt at voicing a little kid didn't sound too good, because Milo is now voiced by Seth Dusky, who is much closer to the proper age.
