fair use of copyrighted footage in language learning context I am making a language learning website. One of the features I want on the website is a collection of videos that talk about various topics in the taught language, so that the members get to practice listening. These could be historical or factual topics, like World War 2 or chinese cuisine, or pop culture topics, like James Bond, Michael Jackson or Super Mario.

These videos would be of an informative nature, but their main function would obviously be to serve as material for language practice. To what degree could I defend the usage of copyrighted material, for example movie footage, in such videos as fair use? And would it affect the situation whether access to the videos was free or not?

EDIT: The website is operated from Norway.
According to this site, Norway does allow exceptions to author's rights for educational purposes, but it does not expand on what said requirements are.  You should probably talk to a lawyer in your jurisdiction for up to date information on your local jurisdiction.
