Until I was about 7 I thought movies had life cycles. All brand-new movies were cartoons. Then when they were older they turned into live-action movies. Then they turned into old grainy live-action movies. After that they turned into black-and-white cartoons, and then into black-and-white movies, and then into silent films. All because someone once told me that black-and-white films were "old movies".
A childhood belief about films

others believed things like this
- I thought that old movies were black and white because the world was black and white then. — K
- I used to believe that the world was actually black and white. (As it is on TV in old movies)— han
- I used to think that black and white TV and movies had originally been in color, but had faded with age.
— Beth - I used to believe that the olden days were black and white when I was about 3 from seing old movies.— Sam
- I used to believe that in old times the world was grey (black and white, i got the idea from old movies) — Bryce
- I thought live-action films were very, very well-drawn cartoons.Anon
