The "Jaws" director is overseeing a remake of the hit series for US network ABC after falling for it, reported Sun online.
"He told me that he and his wife were avid fans of the show and he is now having a pilot episode written for US network ABC, based on the British version," said Kay Mellor, the show's writer.
"He certainly knew everything about the show, which is perhaps not that surprising if he had watched each episode three times," she added.
Kay says she thought she was the victim of a hoax when she was originally told Spielberg wanted to call her about the show.
"My agent said he wanted my mobile phone number, but after four days of waiting for Steven to ring I thought it must be a joke. Then he called me when I was sitting at my kitchen table in casual clothes and slippers, working on the script for 'The Syndicate 2'.
"He roared with laughter when I told him what I was wearing and I promised to send him a picture of me in my slippers - which I did," she said.
