Coraline (2009)'s debt to Being John Malkovich (1999)
Anyone else notice the almost frame-for-frame Coraline (2009) recreation of the hidden, small door (portal) opening to a long, grungy tunnel, leading to an alternate world in the 1999 film? Almost exactly like Cameron Diaz going through the same-sized hidden door, opening on the same grungy tunnel leading to the inside of John Malkovich's head!
In Coraline's first trips, the tunnel is colorful. Later on, it looks exactly like the grungy tunnel of BJM!
Coraline was based on a 2002 book (which I haven't read), but even the book came years after the Malkovich film.
On the plus side, Coraline does one thing I've never seen before: makes buttons look evil!
