initial ideas for article

In order to begin working on my article I will have to research west side story although i have already seen the film I will need to watch it again in order to refresh my memory on the story line. I will also research the origins of west side story and where the idea came from,the characters, choreographer and why they chose the setting among other things. My first stop was YouTube to watch videos on west side story.

In this video we see the jets in their first routine. Immediately we can see the differences between this and Kenneth Macmillan's Romeo and Juliet the surroundings and the costume are completely different even the way the gang talks is current in that time.

The musical itself is about two young rivalry gangs in new york city two members from opposing gangs fall in love - Maria (played by Natalie wood) and Tony (played by Richard Beymer)

whilst researching i found this website : http://www.imdb.com/title/tt0055614/
this website holds a lot of key information on the production including directors and a cast list as well as the budget for the film.
