Wray, who passed away last year (04), starred in the original 1933 giant ape movie as heroine ANN DARROW, and met briefly with Watts before filming began on the new Peter Jackson version.
But Wray's daughter VICTORIA RISKIN admits her mother was concerned about the star's weight.
She says, "They had dinner together with Peter and his wife. My mother told me she thought Naomi was a lovely person... though maybe too skinny. She thought that would be all right."
And Riskin was thrilled by the way director Jackson approached the project.
She adds, "I've seen the original probably a dozen times. There was a little moment where Naomi read her lines when they're getting on the ship, and the lines were exactly as they were in the first film.
"Overall, I think Naomi's performance had the same intelligence, charm and pluck that my mother had."
