Ewan McGregor is holding up the sequel to the movie that made him famous, because film bosses don't want to go ahead without his participation.

Slumdog Millionaire director Danny Boyle is reportedly reteaming with author Irvine Welsh to take the writer's novel Porno to the big screen - 13 years after Trainspotting made the moviemaker and McGregor household names.

McGregor snubbed the picture earlier this year, insisting he didn't want to be part of a "poor sequel", and, as a result filming, has stalled.

And that has annoyed Andrew Lowry, who played Begbie in the 1996 movie - because he's keen to resurrect his character.

He says, "I've always said that I'd do it. Apart from long-running television, I've never played another character twice, but, with Begbie, there's mileage there, with this character there's another place to go. It can confirm what I was trying to do originally with the part, so I would certainly go again.

"It's entirely up to Ewan, but I think it's sad. I think there's more mileage not just in that character, but in the ensemble. And, to have that as a companion piece 12 or 15 years later from that (Trainspotting), it'd be an amazing thing, seeing these characters."
