Apparently we don't have any threads dedicated to that film itself, or to its sequel Ice Age: The Meltdown (2006). We do, however, have threads on Robots (2005) and Horton Hears a Who (2008), which come from the same people (or so their ads say, at least).
Anyway, ComingSoon.net has posted the photo below of an ad for the third film that was recently shown at ShoWest -- and it might lead you to ask, "Uh, but given that the first two films took place at the end of Ice Age -- when there was global warming and humans were hunting sabretoothed cats to extinction, etc. -- how can there possibly be any dinosaurs in the third film? Wouldn't they have been extinct for millions of years already? Did we not, in fact, see a dead dinosaur frozen in the ice in the first Ice Age, and was that gag not a tip of the hat to the fact that the dinosaurs are extinct now?"
