According to Robert Carlyle, there is a Trainspotting sequel, Porno, all ready to roll cameras on. So what is the hold-up? Evidently the dark cloud hanging over its future is a long standing feud between star Ewan McGregor and director Danny Boyle stemming from casting Leonardo DiCaprio in the Beach. Concerning the prospect of taking on Begby again, Carlyle said, "I have to say I've never been approached by anyone about it. I would hope to do it again because we had a great time the last time; some friendships I made on that film have continued to this day, and that's quite rare. The opportunity to work with Danny again would be fantastic."
