The first full trailer for upcoming blockbuster Captain Marvel was released earlier this week. Starring Brie Larson in the title role, the film is the first movie within the Marvel Universe to be helmed by a female superhero - and so it is entirely unsurprising that not everyone is happy about it.

One Twitter user took particular umbrage at the fact that Larson looked serious in the trailer and promotional shots for Captain Marvel (because women have to beam constantly in order to be seen as likeable, obviously). This charming individual ran the images through a photo app to make Larson look like she was smiling, and posted the doctored pictures online with the caption: “I fixed #CaptainMarvel!”

In response, Larson posted a story on Instagram in which she challenged the idea that women should always have to smile. “Breaking news: You can be you,” she wrote.

“That means you can smile or not. You can be strong in the ways you want to be. You can own who you are. If anyone tells you different don’t trust them.”

Larson then shared hilarious images of well-known male superheroes, including Iron Man, Doctor Strange and Captain America, which she had run through the same app. Proving once and for all that a goofy grin looks ridiculous on all superheroes, regardless of gender.
