There was a movie about the age of sail and it began with a clipper sailing along and a man saying something about the islanders had a peaceful culture and it was only natural the white man would come along take its roll it up and out it in his pocket.
Could it be "Bird Of Paradise" 1932 Joel McCrae?
Doesn't look like it, what i remembered wa sa movoie wioth a sailing ship and a voiceover talking about how the islanders had a simnple partadise and it was only natural the whit wman would come, take it, fold it up and put it in his pocket.
That sounds like a line which could've been in a thousand different movies; from Mutiney on the Bounty to The Mighty Gorga.
