Die Gewerkschafterin

When I watched this movie, I thought of those two films : SILKWOOD and ERIN BROKOVICH, starring Meryl Streep and Julia Roberts. Inspired from actual events, it tells the story of the fight between a courageous woman, trade union leader, against world company, and also the "supposed" rape which she was the victim of. She was accused to have invented this rape, and found guilty of this rape.... I did not pay attention when it happened in France, back in 2012. This woman - Irish born - is played by Isabelle Huppert, who seems far younger than her actually 70 years old. But after the watching of this movie, I am still puzzled...Did she really invent this or not? The real Maureen Kearney approved this adaptation, which puzzles me even more.
