Given what we know today about the atrocities of the left in Spain’s civil war, that hasn’t aged well; movies like this one, “Sahara”, and “For Whom the Bell Tolls” were war propaganda movies that all included noble Westerners who had helped or fought for the Spanish Republic - which now we know oversaw the murder of 8,000 Catholic priests (including a dozen bishops), 400 nuns, and countless faithful lay people - who continue to be declared martyrs by Popes (and will be for decades to come).
Rick was complicit in that...
There’s also a line by Isla where she asks “the “boy” on the piano” to play the song.
Look at the difference in movies over the years.
For Whom the Bell Tolls shows the enemy as being supported by nazi, so the Commies were the “good guys” in the war years.
In THE ANGEL WORE RED the “Republican” Spanish were the enemy and the Franco faction the good guys.
In Pan’s Labyrinth, a fantasy which asks which was more terrifying! The Pro-Franco groups or the Commies as opposed to the girl’s fantasy world of strange fauns.(Commies are the good guys in this one)
