Movie Secret Obsession
It’s clear from the start that Vogel’s character was suspicious, so the Secret Obsession plot twist lies in the reveal of why this fake Russell did such a horrible thing, which he explains to her while he has her tied to his bed. He was in love with her for years when they worked together, then the real Russell joined the company, and “took what was his.”
That scene in the bedroom was a tough one for Song to film, the actor said in an interview with Decider. “Sitting there in bedroom tied up, terrified of Russell coming back in…that fear of, ‘Am I about to die?’ is a very real one that I feel like everyone can understand,”
