The actor's only daughter with ex-wife Marsha Garces made her feature film debut as a five year old in 1994's In Search of Dr. Seuss and now, as a 22 year old, she is racking up her movie roles.
Zelda admits she has often had to deal with criticism about following her father into showbusiness and using his famous name to boost her prospects, but she has now hit back in a candid blog post, insisting she works ""twice as hard"" to prove her talent.
She writes, ""While I've never been one to listen to naysayers, I am protective of my friends and colleagues and I've found myself more and more concerned by how negatively people have been treating us of late...
""Success or even participation is often met with claims of favouritism, or nepotism, or perhaps the parent's relevant connections playing a large role in their ascension... Many people don't want to believe that lightning (or in this case the perfect mixture of luck and talent) could possibly strike twice in the same gene pool... I know many 'children of' who are very aware... of the effort it took for their parents to succeed, as well as the chilly reception they will receive pursuing the same success until they 'prove themselves'. It is this very knowledge that usually causes them to pound the pavement twice as hard...""
However, Williams insists having Robin as her father has been her best training for the acting profession: ""I think the invaluable knowledge attained even just growing up around the industry and our parents is our biggest asset as a second (or third) generation entertainer.
""In the end you can't choose the parents you're born to, but you can choose what career you decide to pursue. And whether you want to be an actor, a scientist or a lawyer, if you were born into a family that had succeeded at that very same profession you would want to learn firsthand from their successes and mistakes too.""
