Ewan McGregor's Renton famously announced that he hadn't "felt that good since Archie Gemmill scored against Holland in 1978!" in Danny Boyle's classic Trainspotting in 1996. Now, two decades later, we could find ourselves checking in with the Glasgow addict again, though we doubt he's be feeling particularly euphoric about the state of Scottish football in recent years.

"I don't think there will be any barriers to Ewan or any of the cast coming back.The reason for doing it again is that people cherish the original, people remember it or have caught up with it if they never saw it because they were younger," the filmmaker added.

Another stab at Renton could change that.
