Joan Collins also contracted food poisoning from eating too much of the local seafood while on location (was it Florida?) and looks horrendously blotchy and puffed up round the facial area during the film. For years she hated anyone mentioning the movie. I read a report when a guy tried to get a copy of the video autographed while she was at a book signing and he ended up being dragged away by security.
However, Jonathan Ross discussed the film with her on her recent appearance on his chat show, and they even showed a clip. She seems to have finally accepted it was a stinker !
