“It’s May and June next year we shoot and we’ve got a terrific script… We’ve got the four main actors all eager and willing to do it. I’m very happy because my only (concern) was that the script would be good for two of them and not so great for the other two, and they’d feel obliged to come back, but they’ve all got good stuff, and it’s a very interesting look at them again. Hopefully, we can get it finished in time to release it in 2016 which is the 20th Anniversary year, so yes, we’re on it, and it’s looking good.”
Boyle added that the film was going to be based on the Trainspotting novel author Irvine Welsh’s 2002 sequel book, called “Porno”, but that this particular title has been “set aside” (read: the film sequel is going to have a different title). He had indicated earlier that the four main actors from Trainspotting – Ewan McGregor, Robert Carlyle, Jonny Lee Miller and Ewan Bremner – should all be back, even though Boyle and McGregor supposedly had a falling out years ago.
