It's something I have long thought, but about pictures: Since there is a finite number of pixels on any photo (or image) and the number of colors -perceptible or used- is also finite, it is concluded that the number of pictures or images possible is also finite, but very, very, very large. And a movie is just a sequence of a finite number of photographs, that is, the number of possible films is also finite.
