In Once Upon a Time: The Rock Opera, Vivian Lamolli plays Ursula. Mostly known as the Sea Witch character and the main antagonist of The Little Mermaid. In this incarnation of Ursula, she dances, sings ,and looks beautiful in the way only Lamolli can do it. The movie is all around fun and definitely worth watching. I had a chance to interview Vivian Lamolli and she talked about working on the movie and her career. Plot: Join Emma and the gang and sing along in this zany musical spoof of ABC’s Once Upon a Time.
