20 Best Performances In MCU History (So Far)

Regrettable Iron Man 2 debut aside, there's no denying Black Widow is one of the most important characters in the Infinity Saga, a trained assassin with a shady past who now only cares about doing the right thing and making up for past sins.

Though it took far too long for her to get her own solo movie, Scarlett Johansson was always a blast to watch in the role, acting in many ways like the glue holding the Avengers together and using her sharp spy skills to effortlessly read and help those around her.

Brining Natasha to life with badass fighting skills, dry wit, and heartbreaking selflessness, Johansson's performance is one that simply gets better with every passing film, as she allows Black Widow's biggest secrets and hidden regrets rear their heads in frequently shocking ways.

Like many of the MCU's biggest mainstays, Natasha Romanoff is a character with a striking arc that only gets deeper and more compelling the more you focus on it, and Johansson's performance sells it at every turn.
