Marlene Dietrich was in her mid 50's in this flashback scene from Witness for the Prosecution. Tyrone's character had met her in war torn Berlin years before during the war. This is a particularly heavy scene, and this shot was posed for theatrical stills, and Marlene took the opportunity to look half her age, and very sexy, showing off her famous legs...just one more time. Marlene at any age, managed to make herself look years younger than she actually was. She had an amazing knowledge of lighting and camera angles, as well as makeup techniques. She could virtually tell if her key light was correct by how it fell on her skin. Miss Dietrich of course had had a brilliant movie career by this time, and made fewer and fewer films preferring to sell out her shows in Las Vegas.
She got the idea for this new career from her daughter Maria who told her, just do what you did entertaining the allied troops for four long years during WW2. She did, only she did it more glamorously in specially created glittering Jean Louis gowns. Marlene famously continued to tour the world in concerts until well into her 70's.
