Diane Lane and Kyle MacLachlan have signed on to voice the parents of 11-year-old Riley (Kaitlyn Dias) in Disney and Pixar's upcoming animated comedy Inside Out. We caught a brief glimpse of the parents in the first trailer that debuted in October, but we may see even more of them when the second trailer debuts on Wednesday, December 10. The story is set inside the mind of Riley, as we follow the emotions operating inside her head, Joy (voiced by Amy Poehler), Anger (voiced by Lewis Black), Fear (voiced by Bill Hader), Sadness (voiced by Phyllis Smith) and Disgust (voiced by Mindy Kaling).

During an interview with USA Today, writer-director Pete Docter revealed that the parents play an important part of the story, since Riley is seen through their eyes. Here's what the filmmaker had to say.

"I started out doing a film about growing up, but it turned out it's a film about me watching my kids grow up. These parents are realizing that their kid is changing. That's difficult. But it is a part of life."

Riley's emotions start to get the better of her when she is uprooted from her Midwestern life and moved to San Francisco, where her father gets a job at a new start-up company. Here's what the director had to say about how important Riley's parents are to her.

"These guys are the pillars on both sides. They are pivotal parts, knowing how joyful this kid Riley used to be and the young woman she's changing into."

The film will also explore the minds of the parents as well, with the father's "headquarters" described as, "a Norad missile defense site" while the mother's features, "emotions wearing her red glasses and who engage in civil discussion à la The View." The director also adds that what may seem like a normal event like a family dinner is actually full of drama.

"There's our world which we're conscientious of and looking at. So we're driving, eating dinner, whatever. And inside our head there's this whole rich internal dialogue and world no one else knows about. This film gets you inside each character's heads. We're intercutting to show what's going on inside each of their heads behind the scenes. What seems like a simple family dinner is actually fraught with all sorts of emotional angst and drama."
