Most major movies are still produced on 35mm film. Only around 15% of all movie theaters worldwide have converted to digital. In some areas that is higher or lower but, on average, Hollywood is still 80% or 90% film based.
There are an average of 2 or 3 movies produced by Hollywood per week. (Let's say 2 per week.)
An average of 1,500 to 2,000 35mm release prints are struck for each movie. (Let's say 1,7000 for ease of calculation.)
Your average movie is 120 minutes long.
There are 90 feet of film for every minute of movie.
90 * 120 * 1700 * 2 = 36,720,000 feet of film produced just to meet Hollywood's weekly demand for theater release prints. That's a little over 6, 900 miles of film per week. 27,600 miles of film per month.
The earth is 24,900 miles in circumference at the equator. Therefore, every month Hollywood needs enough film to encircle the world just to meet its demand for movies!
This does not include Foriegn, European and independent movies. This does not include the Bollywood movies produced in India. This does not include film used in the production of movies. (e.g. camera film, duplication and lab film.) This does not include film that ends up on the cutting room floors.
I don't know exactly how much film is produced every year to satisfy our demand for movies but it sure is a lot!
I don't see film going away any time soon.
