“T2: Trainspotting” stars Ewan McGregor, Jonny Lee Miller, Ewan Bremner and Robert Carlyle helped re-create their iconic “Trainspotting” poster with the help of Graham Norton.

The film’s cast and director Danny Boyle dropped by the “Graham Norton Show” to promote the sequel when, citing the original film’s innovative movie poster, Norton pulled out wigs and accessories for the cast to help them re-create their look.

The cast has foggy memories of the original photoshoot, which was held the day after the wrap party.

“I think I remember travelling in a taxi with you at like 5 a.m. in the morning to go to Glasgow airport after the wrap party so we could go down and do this shoot in London,” Bremner recalls to Carlyle, adding he was shocked to discover Miller wasn’t actually Scottish.

“Is that when I blinded you with my Cockney accent?” Miller asks.

“We’d known Jonny for the entire shoot as a Scotsman and then in the taxi after the wrap party, he started talking to me in his own accent. I was really disorientated,” Bremner remembers.

Things got a little more serious during “The Graham Norton Show” when the host brought up the former rift between Boyle and McGregor, who had a falling out over the 2000 film “The Beach”. Leonardo DiCaprio was cast in the film over McGregor, who had until that point been the lead in Boyle’s three feature films.

“It was a misunderstanding and a mishandling of a situation. It was just over a film. It’s a big regret of mine that it went on for so very long and it’s [a] shame we didn’t work together all those years,” McGregor explains. “It didn’t really matter about ‘The Beach’. It was never about ‘The Beach’. It was about our friendship.”

“It made me a bit rudderless. We didn’t speak for such a long time which was really a waste,” he adds.

“I handled it very badly and I’ve apologized to Ewan,” Boyle says. “I kind of feel ashamed about it. I was not proud of the way I handled it. He actually handled it with enormous grace.”
“I was actually so upset about it I actually did ‘The Beach’ with Danny,” Carlyle adds to much laughter.

Thankfully, the pair made up in time to re-team for “T2: Trainspotting”, though not before McGregor and Boyle shared a hilariously awkward 15-hour flight from Shanghai.
