Most parents allow themselves certain fibs to tell their children: Yes, sweetheart, there is a Santa Claus. Your 14-year-old dog Rusty is enjoying his golden years, scampering around a farm. Animated movies were made just for you.

That last lie is in heavy rotation this summer with the release of "Inside Out," a blockbuster that's for the ages and works for all ages. Children may leave the film, which takes place inside a little girl's evolving brain, pining for a toy replica of Bing Bong the elephant-cat, while their folks will wonder why their college psychology classes weren't nearly this thought-provoking.

But "Inside Out" isn't the first animated movie to talk to grown-ups on a whole other level. Here are 10 classics (including the new Pixar film) well worth re-watching after putting the young'n's to bed.
