The 78-year-old Hollywood star, who arrives as Cora's American mother Martha Levinson in the period drama, has described herself as a "jogging pants and tennis shoes" type, reported Daily Express.
"I hated to put that stuff on. I'm not one for wardrobe," she said.
Most of her outfits were sourced from American originals kept in an antique costume house in the San Fernando Valley in California.
"Now that's a once in a lifetime experience, to shoot in such a hallowed place. I enjoyed very, very much that castle and the grounds and the past and the hauntings and the energy. I'm very much into that stuff," she added.
