DARYL HANNAH
The pretty mermaid looked up from the golden sand and the world fell in love with her. The
film was Splash, and the mermaid was the famous actress, Daryl Hannah.
Daryl is tall and slender. She has got long blond hair, large blue eyes and stunning features.
She looks fantastic in expensive clothes, but she prefers casual clothes which show off her natu-
ral beauty.

She is more than just another pretty face, however. She is a complicated person whose char-
acter has many sides. She is often in the public eye, but she is actually a very shy person who
dislikes the crowds and noise of Hollywood parties. Her shyness is a problem which she is trying
to overcome with her friends' help. She is not the sort of person who expects help without giving
anything back, however. Daryl is an extremely caring person, and she says that she forgets her
own problems when she is helping others. She is also a romantic who believes in true love, so she
wants to find someone very special before she starts a family.
Daryl may prefer to sit in the shadows at parties, but when it comes to her beliefs she is not
afraid to speak her mind. She has strong views on the environment. She believes that our mod-
ern lifestyle is destroying the environment. For this reason, she is currently looking for a place
in the countryside where she can build an environmentally-friendly house. She says that she feels
most relaxed when she is close to nature.
It is a pleasure to meet an actress who remains down-to-earth and sincere in a world where
fame and success can often harm one's character! [14]
