This is a creepy movie.
It pretends to be a documentary, but it is totally scripted, totally staged, and feels totally false. It also pretends to be a tribute to Maria Schell by her younger brother Maximilian, and it is filled with so many clips from her old movies that it could make even a devoted fan pray for relief - but in actual interactions between the siblings he's so critical of her and so overbearing that it borders on abuse. Even the supposed ravages of her old age are faked and exploited for the camera, which is really infuriating.
This is a phony, cloying, suffocatingly obsessive movie that indulges Max Schell's obvious obsession with older German female movie stars. It's much like his equally creepy and equally phony "filmed" interview with Marlene Dietrich (only the audio is Dietrich; the video is faked with stand-ins), made practically against her will a couple of decades earlier, not long before she died.
After watching this supposed tribute, I cared less about Maria Schell than I did before, and I lost what little respect I still had for her brother. He was fabulous in Judgment at Nuremberg, but he's come a long way down in the five decades since then.
