We are asked for advice sometimes prior to production, but we don't offer ourselves where we're not invited. However, films are very expensive to make, and if film-makers can know in good time the framework within which the society expects them to operate it can save them a lot of money later. We owe that service to the industry – if they want it. We are sent around two dozen scripts a year, and we make suggestions. Very often the makers will tell us the classification that they want and then we will tell them of any problem areas – things to look at and adjust rather than cut. But we'll also tell them, if necessary, that in our opinion they just can't get that classification without destroying the script entirely.
