Featurette focuses on the special effects that permeate the film, looking at the theories behind the look, the concept art created during pre-production and what it took to shoot the film in 3D, with interviews with Mantle and his crew. Considering how big a part of the film the look is, this is a solid look behind the scenes.

Heroin addict Mark Renton stumbles through bad ideas and sobriety attempts with his unreliable friends -- Sick Boy, Begbie, Spud and Tommy. He also has an underage girlfriend, Diane, along for the ride. After cleaning up and moving from Edinburgh to London, Mark finds he can't escape the life he left behind when Begbie shows up at his front door on the lam, and a scheming Sick Boy follows.
