I picked up a copy of the screenplay a few years ago for £1.95 with a great introduction by the screenwriter. When I looked on ebay to see if there were any books on the making of the film, the cheapest I saw it for was £50, which is nuts. I think there'd be a market for a book about Long Good Friday.. Really interesting that in the introduction he's talking about Hoskins, the producer, director and himself had a perfect sequel lined up and hoped to go into production 1985.
