I thought her part was a good addition to the story. It helps bring montgomery clift's character to age, make him become more of his own man, and most importantly, get rid of those bi-curiosity from the earlier scenes . The scenes were relativly short, and weren't too intrusive. I thought it helped the story thematically. but once it got to that ending, i had a wee bit contempt for her.
Yeah, the arrow scene is pure Hawks. His tough guys need tough women and this is where Dru shows her mettle. Hawks does this, less graphically, in other films--with Jean Arthur in Only Angels Have Wings, for example. It's a kind of trademark.
I loved the arrow scene. It's one of my favorite sequences of the whole film.
Nonsense, If she started crying then Clift wouldn't have loved her. He likes men...err...manly women
