Differences in free speech law geographically? France & Germany are a western countries, have a constitutional protection of free speech, and ban Holocaust denial. The USA is a western country, has a constitutional protection of free speech, and Holocause denial is legal. France, USA and Germany disagree if "banning Holocaust denial" counts as interfering with free speech.

For cinema in the USA, a 9-0 Supreme Court case in 1915 found that movies weren't covered by the First Amendment. That was overturned in 1952 ( https://en.wikipedia.org/wiki/Joseph_Burstyn,_Inc._v._Wilson )

Thank you, exactly what I wanted.
