Because a single film reel does not contain enough film to show an entire feature, the film is distributed on multiple reels. To prevent having to interrupt the show when one reel ends and the next is mounted, two projectors are used in what is known as a "changeover system," after the switching mechanism that operates between the end of one reel on the first projector and the beginning of the next reel on the second projector.

Summertime is the perfect time to take it outside. You can make your outdoor movie theater as simple or high-tech as you like. Unlike flat screen televisions, a projector can easily be moved outdoors for an evening of movies under the stars.
