Production Development Producer Andrew Macdonald read Irvine Welsh's book on a plane in December 1993, and felt that it could be made into a film. He turned it on to director Danny Boyle and writer John Hodge in February 1994. Boyle was excited by its potential to be the "most energetic film you've ever seen — about something that ultimately ends up in purgatory or worse". Hodge read it and made it his goal to "produce a screenplay which would seem to have a beginning, a middle and an end, would last 90 minutes and would convey at least some of the spirit and the content of the book". Boyle convinced Welsh to let them option the rights to his book by writing him a letter stating that Hodge and Macdonald were "the two most important Scotsmen since Kenny Dalglish and Alex Ferguson". Welsh remembered that originally the people wanting to option his book "wanted to make a po-faced piece of social realism like Christiane F or The Basketball Diaries". He was impressed that Boyle, Hodge and Macdonald wanted everyone to see the film and "not just the arthouse audience". In October 1994, Hodge, Boyle and Macdonald spent a lot of time discussing which chapters of the book would and would not translate into film. Hodge finished the first draft by December. Macdonald secured financing from Channel 4, a British television station known for funding independent films.
