Why Bergman won the Oscar...
Honestly I don't think it was really a bad performance at all, and I have no problem with her win. But the Academy saw her interrogation scene, most of which was done with no cuts, and were thouroughly impressed with Bergman's work. She was also sick at the time, which helped her tally up more votes.
Do youu think she deserved her Oscar?
