In the last decade, Scarlett Johansson’s Natasha Romanoff, also known as Black Widow, has appeared in eight Marvel Cinematic Universe films. After her career as a spy, she joined the superhero team the Avengers and was integral in several battles during the Infinity conflicts.
There have been a lot of superb spy moments in the Marvel movies, but these eight are my favorite. I’m of course going with eight because of spiders having eight legs. Seemed appropriate.
