Could you please check over the following paragraph, which is part of my essay, im not sure whether im using the harvard method correctly. Im using all the information on this essay from a book form the library, it says that its by Paul Scanlon, Michael Gross and edited by Charles Lippincott, but it does not say who wrote what in the book, and it also does not have page numbers. Shall i count them out started from the first page of writing?
I will start this essay off by giving a brief description of the build up to the pre production and concept stages of Alien (1979). Before i start i will state one sentence to think about after a shaky start to the development of the story. 'Twentieth Century Fox wanted to make sure that the sixteen weeks of principle shooting would only be witnessed by authorised eyes.' (Paul Scanlon, Michael Gross, 1979: pg 01 'The Book of Alien') What Paul Scanlon and Michael Gross, the authors of the book appear to be saying, is that the shooting and set design of the movie was to be kept a great secret from the public, and only people working on the set was allowed to see it. However a pass from the production manager would allow a visitor a glimpse of what was going on inside.
