Outline for the Third Term Paper

Green screen
Intro:
A. One of the most common and cheapest effects in movies and tv shows
B. Actors and foreground scenery placed in front of a green screen, which an image is then placed digitally on the green screen
C. Used in place of expensive scenery, making a scene able to film indoors.

Use in Harry Potter
A. Used in many scenes, mostly commonly in scenes with large landscapes, caverns, and most notably, quidditch.
B. Often used in scenes where magically properties use, especially every flying scene. It is almost impossible to tell it's green screen.

Use in Whose Line is It Anyway?
A. In a more humorous fashion, this show uses it in the game appropriately named "Green screen"
B. The "on the field reporter" (usually Colin or Ryan) stands in front of a green screen while two other performers acting as reporters back in the newsroom ask the field reporter questions. The field reporter, based on those questions, has to guess the image being projected on the screen. It is hilariously unrealistic.
C. The reporters usually hint at what's going on using puns.

Conclusion
Green screen is everywhere, and even the most amateur of film makers can use it, as long as they have the appropriate software. Don't wear green when you use it, otherwise you'll blend into the background. I didn't know we had to do the outline until it was almost too late so this is really last minute and I'm a horrible person and I'm sorry.
