Jessica Alexander plays Vanessa in Disney's live action version of The Little Mermaid. Vanessa is Ursula's human alter ego, which she uses to sabotage her deal with Ariel. She described her character as "a seductress, a temptress, the definition of a femme fatale and a sexy female villain."
Plot[]
Eric takes Ariel sightseeing around the kingdom. Sebastian, who has followed Ariel, realizes that Ursula (Vanessa) has put a cheat in the spell that is causing Ariel to forget that she needs to kiss Eric. Along with Scuttle, a northern gannet, and Flounder, Sebastian takes it upon himself to get the pair to kiss. They are almost successful but are thwarted by Ursula's eels. Enraged by the close call, Ursula turns into a human and uses Ariel's siren voice to hypnotize Eric. Back at Atlantica, Triton has the kingdom search for Ariel and begins to regret the way he treated her.
The next morning, Ariel and her friends discover that Eric will be announcing his engagement to "Vanessa" (Ursula's alter ego) later that day. Ariel rushes to the engagement party, confronts Ursula, and breaks the shell. She gains back her voice, and the enchantment on Eric is broken. However, before they can kiss, the sun sets and Ariel transforms back into a mermaid. Reverting to her original form, Ursula drags Ariel back into the ocean.
In the bonus short, Vanessa became a good girl.
