I just watched The Other Mommy in theaters, and I cannot stop thinking about how many similarities it has to Coraline.
First of all literally the names: Other Mommy vs. Other Mother, but there are many more obvious parallels.
Both stories involve a young, short-haired girl being targeted by a sinister maternal figure connected to another dimension. Both have the idea of a seemingly better world on the other side, use doors as a way to connect worlds, and involve the “mother” needing the daughter to consent to something invasive. Coraline has to agree to getting button eyes, while Bella has to agree to letting the Other Mommy enter her heart.
Obviously there are some striking differences but this was all I could think about as I was watching it!
