My name is Kara White Castro and i am a Scriptwriter. I have been a scriptwriter for over 20 years now and it has been the greatest job of my life.  I am best known for the american TV series Big Bang theory and the multi-award winning TV series Game of Thorns. I was born in Birmingham in 1976 where i grew up and in 1995 i sent a piece of a screenplay i had wrote in university to the director of Eastenders, where he got in contact with me to come and wright for the show. So in 1995 at the age of 19 i packed up and moved to London to assist the leading scriptwriter for the show and so my journey began. To follow on after working for Eastenders for 8 years, my talent was noticed by the director of hit TV series Big Bang theory, which had not even been aired yet, I then accepted the job and up and moved to america. Then to follow on after working there for 5 years my talent was then released by the director of the  phenomenal TV series Game of Thorns. I then jumped at the chance to take on the main lead role of scriptwriter for the series and have been doing that for 4 years now and hope many more to come.
