Arguably more cinema vérité than documentary, D.A. Pennebaker’s Don’t Look Back follows four weeks of Bob Dylan’s solo acoustic tour across England in 1965. Virtually absent are the standard documentary conventions of archival or interview footage. Nor is the film a concert picture, with very few live numbers captured in their entirety, and more than half of the film following Dylan backstage and between gigs. Instead the camera acts solely as a fly on the wall and for 96 minutes the viewer watches Dylan ongoing evolution as performer and personality. Here’s hoping he’s evolved since.
