Alanis Morissette Featured in Exclusive New "Milky Way" Trailer Touting Breast-Feeding

— -- Singer Alanis Morissette and health experts speak out in a trailer for an upcoming film that advocates for more moms to breast-feed their babies.

"This is a huge movement that needs to happen right now in America," a lactation consultant says in the trailer for "The Milky Way Movie" that was released first to ABC News exclusively.

More celebrities set to make appearances in the full feature are actress Minnie Driver, model Justine Pasek and more, according to the group behind the film, The Milky Way Foundation, an advocacy group whose mission is to get more women to breast-feed.

“We’re trying to come at solving the world’s problems from the symptomatic stuff back,” Morissette says in the new clip. “I think it would be so much easier to start from the beginning and work up.”

A national breastfeeding report by the Centers for Disease Control and Prevention found that about 77 percent of infants begin breast-feeding at birth. That number drops to 49 percent by six months and 27 percent by 12 months.

"I like to be sensitive to women who don’t breast-feed for whatever reason," said Dr. Jen Ashton, ABC News' senior medical contributor. "Medical literature shows there are long and short term benefits to breast-feeding but you can only do what you can do.

"As a mother, you already have more than enough guilt to go round," she said. "I try to give women a little empathy on that because I know it’s not possible or feasible for every woman to breast-feed her baby. Every woman’s choice should be respected. But medically it’s clear there is a benefit."

"The Milky Way Movie" will make its global debut digitally and on demand on May 5, according to The Milky Way Foundation.
