Scarlett Johansson

Arm bra or hand bra? And what exactly is the difference? We'll explain, with the help of Emily Ratajkowski, Emmy Rossum, Nina Agdal, Kate Upton, Scarlett Johansson, Genevieve Morton and more.

Some of the leading ladies of Hollywood get wet and wild as they get their splash on.

So, so talented. Also: great boobies.

With Robert Downey Jr. and Chris Evans promising a big surprise on Jimmy Kimmel Live, we knew it had to be something special — that something is the first trailer for Captain America: Civil War. Not a teaser, but an actual, full trailer, dramatically highlighting the growing divide between Steve Rogers and Tony Stark, which will divide the Avengers and pit them against one another in what could be Marvel's most epic film yet.

It’s not coincidence that Scarlett Johansson guest hosted SNL on the same weekend that Avengers: Age of Ultron opened in theaters, so of course the show had to do a Marvel sketch of some kind. And unlike the previous Avengers sketches cooked up for Chris Hemsworth and Jeremy Renner, this one is actually a pretty effective dig at the Marvel movie machine. More importantly, it’s very funny.

Featuring some returning favorites and one dynamite newcomer.

The only thing better than Scarlett Johansson is a naked Scarlett Johansson.

The desire for (and subsequent lack of) a female-led superhero movie is a hot topic that continues to be debated. Actually, there really isn't much debate; we're all pretty much in agreement that there should be a female-led superhero movie. Well, you can add one more voice to the chorus of people shouting loudly for a female Marvel movie as two-time Oscar-nominee Jessica Chastain took time out from her current promotional tour to support the notion of a Scarlett Johansson-led Black Widow movie.

In the last year, Scarlett Johansson has voiced a sentient operating system in Spike Jonze's 'Her' and played an alien striving to understand humanity in Jonathan Glazer's jarring 'Under the Skin.' This week, she tackles a different kind of sci-fi with 'Lucy,' a film that carries some of the same thematic DNA as her previous roles, though it isn't quite as intellectual -- nor is it as brainy as its titular character. But thanks to Johansson, the film prevails, giving us a wild and delightfully weird entry in the Scarlett Johansson Sci-Fi Collection.
