Documentary on dolphin assisted therapy

She played a mermaid in her most notable film role, "Splash," more than two decades ago, so it's not a stretch for Daryl Hannah to lend her time and talent to the Angel Foundation of Hawai'i's production of "Na Nai'a: The Dolphins," now filming on the Big Island. Hannah's been staying at the Sheraton Keauhou Bay Resort & Spa.

The documentary focuses on dolphin-assisted healing of children and adults with cancer, handicaps, autism and terminal illnesses. In addition to location work at the Sheraton Keauhou Bay, sequences are planned in the waters off O'ahu, Maui and Lana'i, and in Russia, Canada, Switzerland, Florida, the Amazon, Australia and New Zealand.
