There are a couple of British movies from the 60's I would like to see again, but can't remember the titles. Vague childhood memory. One was a science fiction about a revolutionary pop culture icon in the near future. It ended where he denounced everything in a speech, and the movie showed the speech as the last thing that existed of the guy and the sound was removed, which I guess was a statement on totalitarianism.

Another 60's movie was a type of comedy and featured a spoof commercial for a super 8 movie camera, I think they called it the "Hamshika Super 8", the last showed a bunch of people tossing the cameras in a dumpster.

I can identify the first one, as it's one of my all-time favorites.

Privilege (1967)
Starring Paul Jones, Jean Shrimpton
IMDb synopsis:
Steven Shorter is the ultimate British music star. His music is listened to by everyone from pre-teens to grandparents. He has no trace of public bad habits or drug involvement. Everyone in Britain loves him. His handlers begin to use his popularity for projects like increasing the consumption of apples after a bumper crop as an aid to farmers. The handlers decide that Steven should support God and Country next. This leads to, among other things, a rock version of "Onward Christian Soldiers," and the inclusion of a Nazi salute to make it clear (to the viewer) how far the British population will be taken for love of God and Country under Steven's guidance. Steven is very plastic in his direction, shifting as his handlers point him toward new projects until he meets Vanessa Ritchie, an artist who makes him look at what's happening.
