Actress Mackenzie Foy found a friend in her "The Nutcracker And The Four Realms" co-star Keira Knightley, and says she is a nice and down-to-earth person.

"Keira is just amazing. I've really enjoyed working with her. She is such a nice, down to earth person. You can literally talk to her about anything and she would just listen and be a good friend," Foy said.

Asked about her favourite moment working with her, Foy said: "I don't know. We have spent a lot of time together but I think pretty much when we could just relax on the set and we could just sit and talk about nonsense. It was really fun just to get to know her."

"The Nutcracker And The Four Realms" is the retelling of ETA Hoffmann''s short story "The Nutcracker And The Mouse King" and Marius Petipa's and Pyotr Ilyich Tchaikovsky's ballet "The Nutcracker". It's a story of a young girl who gets a locked egg as a gift from her deceased mother, and narrates her magical journey to get the key for the egg.

"The Nutcracker And The Four Realms" will air in India on Star Movies on May 10.
