RBG was released just a couple weeks after the record-breaking Avengers: Infinity War and, even though one is fact and the other is fiction, the two have more in common that one might expect for a documentary and a science-fiction/fantasy epic. They both feature superheroes, the woman at the center of RBG being much more of an unlikely one than the expected ones in Avengers.
