Ominously billed as "a journey into the origins of modern yoga", this one's niche, to say the least. German documentarist Jan Schmidt-Garre has gone to India and brought back a wearyingly attenuated history of stretching: footage of sages discussing stretching, intercut with footage of people stretching, and scratchy archive footage of people stretching in olden times. (It hasn't changed much.) Schmidt-Garre does little to turn this scholarly exercise into cinema, and his Teutonic seriousness is grinding when not ripe for parody. Where's Mad Lizzie when we need her?
