There are a lot of freeze-frames in T2 Trainspotting. To an inattentive viewer, they might look like empty style for style’s sake, or a nod back to the flashy visuals and hyperkinetic editing of the original Trainspotting from 20 years ago. But the freeze-frames also turn the film’s subtext into text. T2 is about a group of immature men coming to grips with the fact that they are getting older. The freeze-frames — along with a steady stream of flashbacks — enable the film to do the very thing the characters wish they could do, but can’t: Stop the inexorable march of time, and even, for brief moments, turn back the clock to their youths.
