According to the accompanying booklet of the Arrow DVD, Argento had wanted either Jennifer or Bridget Fonda for the role of Anna because of their performances in SWF. I think Leigh would have been terrific.
The world forgetting, by the world forgot Eternal sunshine of the spotless mind
I agree, J.J.Leigh would have been great in this story but there would have been a problem : because of her so famous performance in "Single White Female", people could have guess that she was the real criminal . Don't you think so ?
There was an article about Argento's TRAUMA - I think in Cinefantastique, not Fangoria - in which he talks about the planned project with Fonda signed on. It was originally to be shot in Arizona.
I don´t think it would have worked well as an american version, and I don´t mean comercially, but it would have turned into a much less interesting movie.
