In a lot of websites it is written that Lesley-Anne Down participated to 2 early episodes of the 7th season of "Dynasty" ("Focus" and "Reward") as "nurse Ellena Corey".
Of course, that's not true but why even IMDB mentions it?
Do you think she participated to the show but that her appearances were eventually cut out for some reasons?

I don't think so but Lesley is great actress!
She is english lady like Joan Collins
I love her in "Sunset Beach" and "The Bold And Beautiful"

Lesley-Anne Down replied on the forum of her official website that she never participated to any episode of "Dynasty", however the bible of season 7 (*) mentioned a nurse (called Andrea Kyle) that Krystle hired to take care about Blake while she was having her brain tumor (a story that was erased and used instead in season 9).
The bible said that Krystle would die or live depending on (I quote) "disclosure of the actress' plans for next season" and implied that Andrea Kyle would have became the new wife of Blake if Krystle had died. It's possible that the producers had casted Lesley-Anne Down to replace Linda Evans before Linda Evans changed her mind about staying in "Dynasty" for a couple of seasons.
