I'll agree to being confused. Thanks for being more useful than the other commenter and providing some helpful information.

Here's the definition I'm using, from dictionary.com:

"adj. of or pertaining to a mechanism that represents data by measurement of a continuous physical variable, as voltage or pressure."

It's easy for me to see how a video cassette fit this definition, as it is a record of voltage. I can believe that film also fits the definition but I'm not a chemist. What's the continuous physical variable recorded on film?

OK, anonymous coward. In fact I am in school and am quite open to learning. Take the opportunity to educate rather than insult.

Not "analog," but optical. Film is storing the actual picture, not an electromagnetic representation on magnetic tape. It should be noted that all that is not digital is not necessarily "analog."
