Danny Boyle's "Trainspotting" put the Oscar-winning "Slumdog Millionaire" director on the map in 1996 along with his cast of then-unknowns Ewan MacGregor, Robert Carlyle, Kelly Macdonald, Jonny Lee Miller, Kevin McKidd and Ewan Bremner -- all of whom have gone on to varying degrees of success. Now, Boyle says that a long-in-the-works "Trainspotting" sequel could become a reality with the original cast on board.

"This has been a long time coming," Boyle told The Playlist after revealing footage from his upcoming film "Trance" at the SXSW Film Festival. "There's always been this long-term plan for 'Trainspotting 2.' If [original screenwriter John Hodge] can produce a decent enough script, I don't think there will be any barriers to Ewan or any of the cast coming back."

Boyle said, "I think they'll want to know that the parts are good so they don't feel like they are letting anyone down. 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 because they were younger. So you want to make sure you don't disappoint people. That will be the only criteria, I think."

Hodge is currently penning the sequel, which will be a "loosely-based" adaptation of "Trainspotting" author Irvine Welsh's own sequel, titled "Porno," and Boyle hopes to make the film in 2016.
