《后窗》的结尾，怎么一回事？

  今天看的彩色修复版，听说结尾和原始公映版不一样。修复版结尾有个疑问，杜警探为什么要对那个给男主角看病的女士说“你要不要看看。”，给男主角看病的女士一听后反映很奇怪？想问原始公映版是什么样子？

后窗本来就是彩色的吧，，
下面是53年最终版的电影脚本，

Stella tugs at Doyle's arm and stands on tiptoe to whisper
    something into his ear. Doyle then looks up to the detective.

                          DOYLE
              Did he say what was buried in the
              flower bed?

                          DETECTIVE
              Yeah. It's over in his apartment. In
              a hat box. Wanna look?

    Doyle turns quizzically at Stella.

                          STELLA
              Oh, no thanks -- I don't want any of
              part of her
                   (She pauses, then
                   does a surprised
                   take back to Doyle)
              What did I say?
