If you are a unitedstreaming subscriber and you're interested in video production in your classroom you absolutely MUST see the series of nine videos from the American Film Institute entitled Lights, Camera, Education!
The videos range in length from about 8 minutes to 37 minutes, and will walk you and your students through the entire movie making process from pre-production through post-production, viewing and reviewing student projects, and even student reflection on the project.
There is also an 88 page teacher guide that correlates to the process. To download it click on the "Related Materials" tab for any one of the Light, Camera, Education videos in unitedstreaming.
unitedstreaming rates the videos as appropriate for grades 9-12, but I believe the lessons could be adapted for younger grades. The videos are hosted by actor Sean Astin, best known for his roles in Rudy and The Lord of the Rings.
