She might have been wearing a body suit.
It’s probably the role we will always remember her for but she definitely wants to forget it happened. She even tries to claim it was a “body double” but it’s obvious it isn’t. To be honest, I always thought her acting was quite bad in El Condor. I’m not too familiar with the rest of her work with the exception of The Godfather Part II and High Plains Drifter but it’s clear that she was just meant to be eye candy in El Condor for male viewers. It would be nice to ask Jim Brown about his experiences and whether he remembers any other scenes. We need a Blu-ray with some extras! Only problem is that Warner don’t licence to people like Arrow who could probably do more it justice. I think they wouldn’t have too much of a problem with sales, especially since Lee Van Cleef’s westerns are becoming more popular among new movie fans. The content alone would probably sell it. I’m sure it would still get an 18 certificate in the UK.
