Chances are you've seen set pictures of actress Brie Larson wearing a blue and green proto-Captain Marvel costume during the shoot of Marvel's upcoming solo film, Captain Marvel -- but we have yet to see the superhero in her official, blue, red, and gold suit. One of the main questions regarding Carol Danvers' cinematic look was if she would be sporting her signature battle helmet in the film. Well now, thanks to a new piece of key art from the film, it appears we have an answer.

Yesterday, actor Samuel L. Jackson, one of the stars of the '90s set Captain Marvel, shared a picture of himself on his Instagram page wearing an official visual effects crew t-shirt from the movie's production. The shirt, which is clearly marked with "Captain Marvel Visual Effects" on its side, features a new look at Captain Marvel's movie costume, this time with the appropriate red, gold and blue colors. But even more importantly: she can be seen wearing her battle helmet, complete with the Mohawk hairstyle.

What's more, Jackson's mention of Thanos in the caption's hashtag would all but confirm that this t-shirt is giving us an official look at Marvel's live-action Captain Marvel.

Carol Danvers' Mohawk-helmet look debuted during the character's Marvel NOW! relaunch in 2012, and it quickly became an iconic look for the female superhero. If Jackson's new t-shirt is any indication, then the signature look will make the jump to the big screen when Captain Marvel makes her big screen debut next year, before joining the fight against Thanos in Avengers 4.
