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, who has
also starred in such films as Roxanne and Blade Runner.
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 natural beauty.
She is more than just another pretty face, however. She is a complicated person
whose character 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's lifestyle is quite simple. When she is not working, her favourite activities are
gardening, playing the piano and making pottery, all of which reveal the creative side of her
character.
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 modern 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.
Underneath the success, shyness and simple lifestyle are Daryl's very strong views on
life. As she says, "Find out what is important to you - and don't be afraid to leave it!"
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.
