Owen had memorized every line from every Disney movie. And the family now realized by speaking in those characters' voices, they could communicate with their son. The suskinds would spend several years immersing themselves in Owen's world. We were living a kind of double life. I'm interviewing presidents. And at night we're animated characters. What did you feel when you were watching those movies? Felt like I was in a better safe place. The world was so noisy coming at him, overwhelming him. As Cornelia said, the movies were the one thing that didn't change. One thing that can happen with Disney movies is children will learn parts of the script -- Reporter: Dr. Landa, who spent 20 years working with children with autism, says it's important to pay close attention to what they're trying to express.

They use these passions as codebreakers to crack the codes of themselves, their place in the world action their identity. Reporter: A lesson for parents of children with autism who worry their kids are too obsessed with certain subjects. It can be a good thing, says Dr. La Landa.

Reporter: One of those new experiences, real-life interaction with an animated character. This Broadway performance of "Aladdin" was held specifically for people with autism. Jonathan and his mom were eager to attend. Usually when I go someplace, I'm all stressed out because Jonathan is sometimes unpredictable with his behavior. Here, I'm not worried at all.
