which type of media is used in cinema halls to run the show viz. celluloid film or electonic media like DVD?

Answer 1

Most I've been to are still film reels, with varying quaity. You can read a lot about the different kinds here: http://en.wikipedia.org/wiki/Movie_projector

Answer 2

Most theaters still use film projectors, but the trend is toward all-electronic "digital" projection. Eventually that will overtake the film entirely, mainly for economic reasons. Film prints and distribution are expensive, and electronic distribution (by DVD or other means) is relatively cheap. Until recently there was a big dispute as to who was to bear the cost of theater upgrades ($100,00 to $200,00 per theater). The theater owners thought that the studios should share the cost because they get the most financial benefit, but the studios resisted. Now there is a cost-sharing agreement, and you will see a rapid conversion to electronic projection. While under the best conditions, film projection still gives the best quality picture, most neighborhood theaters are far from the best, and the switch to digital will be a noticeable improvement in quality. In addition, the digital "print" doesn't get scratches, doesn't wear out, and won't break. So you can see a movie that has played for months in the same theater at the same quality as when it first came out.

Answer 3

I worked as a projectionist for many years. Movie Theatres still use film. 35 millimeter in standard theatres and 70 M.M. in IMAX and other select Theatres.
