Downfall parodies removed

The 2004 film, Downfall is very well known for its parodies. A scene in the movie, when Hitler going into a rant about the war is used and then english subtitles are placed so that people could make a parody. In April 2010 Constantin films asked youtube to block all downfall parodies. Doing this caused much uproar an shows the strain of copyright laws for the visual media. Many people have different opinions about how fair this is because the makers of the parodies advertised the films and made no money. This has been a central debate on copyright in films in the last year and much more could follow.
