1) The 'welcome home' cake in Coraline features a double loop on the O. Graphologically, a double loop on a lower case O means the person who wrote it is lying. As there is only one double loop, it means she is welcome but she is not home.
2) In Tarantino's 'Pulp Fiction', Mia outlines the assassins in his other film 'Kill Bill'. In fact, Tarintino has stated that many of his films exist in the same universe, where the events of 'Inglourious Basterds' lead to a desensitised, hyper-violent world.
3) For Christopher Nolan's 'Interstellar', he planted five-hundred acres of corn, specifically for the film, so as to avoid CGI. After the filming, he had the corn harvested and sold to profit the budget.

4) In Scorsese's 'Shutter Island', so much of Teddy Daniel's reality comes down to the visuals of fire and water.

7) In the film 'Titanic', a woman is seen telling her children of "Tír Na Nóg, The Land Of Eternal Youth And Beauty". In Irish mythology, this land can be reached by going underwater or across the sea.
8) In 'The Matrix', when Neo is being dragged out of the office building at the beginning, every cut of the scene has a woman in red passing by. Red is symbolic of not only warning but of courage and sacrifice.
9) Furthermore, in this same Matrix scene, the Wachowskis used multiple set of twins, to create the feeling of a copy and paste world.
