Isabella Rossellini, well known as a supermodel and movie star, is now making short films for mobile devices that illustrate the sex lives of dragonflies, earthworms and other creatures. But they are not like standard nature shows. In these films, which she researched with the help of Wildlife Conservation Society experts, she not only details unusual aspects of the critters’ biology but also dresses up as them and mimics sex with paper cutouts. We asked Rossellini what she hopes to accomplish with the films on invertebrate love, dubbed Green Porno, which premiered May 5 on the Sundance Channel’s Web site.
