She also revealed that she has forbidden her three-year-old daughter, Edie Knightley Righton, from watching these movies.
Knightley is now making the rounds to promote Walt Disney Pictures' upcoming movie "The Nutcracker and the Four Realms".
The issue? The way women are portrayed in films like Cinderella, which Knightley says is banned from her home because the princess "waits around for a rich guy to rescue her". Don't! Rescue yourself. Obviously!
And it's not just Cinderella, Knightly has banned The Little Mermaid as well and with a heavy heart because she loves that one. "Little Mermaid. I mean, the songs are great, but do not give your voice up for a man. Hello!"
Not all Disney movies are off-limits.
"'Frozen" is huge and "Moana' is totally fine".
The mother also talked about her daughter's wild aspirations in life. "Even if she wanted to be an actress I'm going to support her in anything she wants to do".
"It's changed. She did want to be a dentist, which I was super happy about", Knightley shared. "I'm not sure why, she loves Peppa Pig and fell in love with a dentist episode", she laughed.
'Now she wants to a be a lion, she roars very well.
But a person in a store once asked her to pose for a photograph ― believing she was pop star Britney Spears, Knightley told host James Corden.
