Isabella Rossellini stars in bug-sex promos

It’s been more than 20 years since Isabella Rossellini got naked in David Lynch’s Blue Velvet. Most of us assumed her saucy phase had passed, but now the actress returns with “Green Porno,” a series of bizarre two-minute films commissioned by the Sundance Channel and intended for viewing on cell phones. She portrays a fly, a spider and an earthworm to show how small creatures reproduce, and co-stars in the vignettes with cardboard cutouts as she demonstrates various “techniques.”
