Marvel’s 'Black Widow' refuses to stay dead

In the movie world we’re used to sequels — “Fast & Furious” is up to 12. And occasionally we see prequels, a story that takes places before another movie, like “X-Men: First Class.” And what about all those “Star Wars” episodes — weren’t they out of proper order?

Marvel Studio’s Kevin Feige calls his new superhero blockbuster “Black Widow” a prequel, comparing the film to the television series “Better Call Saul,” which is a prequel to “Breaking Bad.” He says it was “a wonderful example of a prequel that almost completely stands on its own ... but it informs you about so many things you didn’t know about before.”
