Interesting Fellini, but far from his best...
“Orchestra Rehearsal” is an allegorical pseudo-documentary depicting an Italian television crew’s visit to a dilapidated auditorium to meet an orchestra assembling to rehearse under the instruction of a tyrannical conductor. The TV crew interviews the various musicians who each speak lovingly about their chosen instruments. However, as petty squabbles break out amid the different factions of the ensemble, and the conductor berates his musicians, the meeting descends into anarchy and vandalism. A destructive crescendo ensues before the musicians regroup and play together once more in perfect harmony.<br /><br />This short film by Federico Fellini is problematic because the director attempts to have the orchestra serve as metaphors for many issues —  social class, society, history, politics, unions, and art. The musicians do not have distinguishing personalities and there is no traditional plot to follow. Though the musicians protest, the film offers no solutions and no distinct goal. Fellini manages to provide some affecting monologues, but the film as a whole never catches fire.<br /><br />“Orchestra Rehearsal” is unfocused. its collection of episodic moments should come together eventually to make a point. As an allegory, it is simplistic and obvious. The viewer awaits a climactic sequence that never materializes. The German conductor and his authoritarian manner suggest Hitler, with the musicians representing the masses, dutifully following orders. But the format of a rehearsal is an awkward fit for the points Fellini is making. A traditional, dramatic feature would probably have worked better.<br /><br />Bonus materials on the unrated Blu-ray release include film scholar Richard Dyer discussing composer Nino Rota and his contribution to “Orchestra Rehearsal;” “Orchestrating Discord,” a visual essay by Fellini biographer John Baxter; gallery featuring poster and press material on the film; reversible sleeve containing two artwork options; and an illustrated collector’s booklet.
