Jonny Lee Miller had to "dodge people" when he was filming 'T2: Trainspotting'.
The 44-year-old actor stars as Simon 'Sick Boy' Williamson in the sequel to the hit 1996 drama film 'Trainspotting', and has said the popularity of the first instalment made filming the long awaited second part was "a little bit challenging" as he found he was having to "lose photographers" more often.
The movie, which was filmed in Edinburgh, Scotland, sees Jonny and his original co-stars - Ewan McGregor, Robert Carlyle and Ewen Bremner - battling their addictions and reigniting past clashes.
Jonny told People magazine: "There's the challenge of like, when you're shooting 'Trainspotting' and everyone knows you're shooting 'Trainspotting' - [Director Danny Boyle] said it's like Scotland's 'Star Wars'.
"When we made the first movie, no one cared, right? No one knew who we were or what we were doing.
"[The sequel] was a little bit challenging because you've got people paying attention to you and it just sort of changes everything a little bit. You have to try to dodge people and try to lose photographers, and try and mask what you're doing because you don't want it ruined for everybody."
Meanwhile, Jonny said he decided to return to the role for a 'Trainspotting' sequel because he had "faith" in director Danny Boyle, who won the Best Director Oscar for 'Slumdog Millionaire'.
He said: "I always felt (a sequel) was a possibility. And I had faith in Danny Boyle, I really do. I know that he's not going to pull the trigger on something if it's not right."
