Lou, you are correct. I googled the movies and other's that might be related to AK but no luck. With few rides/shows at opening, there's not much they could have movies based on. Aladar and Flik (the main character) among all the other characters in those two movies did premier before the release dates of the movie, but went into production for AK after the movies had already been started. So technically the characters premiered first in the movies, just not publically right away.
