Corrected entry: When Katherine reserves a room at a hotel she talks German. From her weird diction it's obvious that Sigourney Weaver has somehow memorized the text without actually knowing what she is saying. (00:21:50)
Correction: From Ms Weaver's IMDb page: "Speaks French and German fluently."
Corrected entry: When Jack arrives at Katherine's apartment, he rings her intercom from the street entrance. She instantly answers and buzzes him in, even though she's laid up in bed with a broken leg. There's no intercom near the bed, and she could not have gotten to the one by the front door that quickly, hobbling around on crutches and a cast on her leg. When Jack comes up, she's still in bed, sitting in the same position as when Tess left a few minutes before Jack's arrival.
Correction: There is an intercom by the right-hand side of the bed.
Corrected entry: Tess' lunch box from Jack has the initials T.M.T. on it as if she and Jack got married; but when she goes to the new job she introduces herself as Tess McGill.
Corrected entry: At the beginning of the movie Tess goes to work. When she enters the building she is wearing a brown coat. When she arrives at the office she is wearing a grey jacket. (00:03:45)
Correction: The brown coat was a heavy winter outer coat. The grey jacket is a lightweight jacket that goes with her outfit.
Corrected entry: When Tess catches her boyfriend Mick having sex with one of her friends in their bedroom Mick is shocked and embarrassed, but the girl just keeps going as if nothing was happening. It's pathetic acting. (00:29:00)
Correction: Not really. She, in fact, does stop and her eyes move slowly to Tess. Then when Mick is trying to talk his way out of it, Doreen puts her arm on his shoulder and puts her face in her hand, also embarrassed. She IS still breathing hard, however, because the sex abruptly stopped.
Correction: Sigourney Weaver apparently knows German, so this mistake is wrong. Also, it sounds like she is conversing in German like a natural, and it sounds like conversational German to me.
Unless it's known that Sigourney Weaver knew German prior to 1988 this correction is wrong. Also, how she is talking, be it sounding memorized or natural, is personal perception. This alleged mistake has no supporting evidence so doesn't deserve to be an entry here.
