A new documentary attempts to grapple with the late, great American auteur. You’d learn a lot more by rewatching his films…I wish that Ron Mann’s affectionate but inch-deep Altman was the great documentary biography that Robert Altman warrants, but it isn’t. Mann’s biopic would make a fine accompanying documentary to my fantasy box set of The Complete And Utter Works Of Robert Altman, and its use of clips from a solid majority of the director’s movies makes it a mouth-watering appetiser for anyone eager to reacquaint themselves with the master’s entire oeuvre.
