A new video from the set of Captain Marvel shows Brie Larson in her heroic getup preparing for a fight scene with an unidentified man... on top of a train.Considering that Skrulls appear in the film, and they have the ability to shapeshift, it's likely Marvel is dealing with an alien rather than human in the scene. The film is believed to be borrowing elements from the comics' "Kree-Skrull War" storyline, which saw Earth and the Avengers get caught up in the years long war between the two races, so the presumption that there's more than meets the eye here carries some weight.RELATED: Where is Captain Marvel During Infinity War?

Previous glimpses of the film have included the initial photos that revealed Carol Danvers in her Kree military uniform inspired costume, while mst recently, photos of Samuel L. Jackson as a younger, much less bald Nick Fury made their way online. While we knew Fury, along with Clark Gregg's Agent Phil Coulson, would play a role in the film, that was the first look at any of Captain MArvel's major players aside from Larson.

Directed by Anna Boden and Ryan Fleck, Captain Marvel stars Brie Larson as Carol Danvers/Captain Marvel, Samuel L. Jackson as Nick Fury, Jude Law as Walter Lawson/Mar-Vell, Gemma Chan as Minn-Erva, Clark Gregg as Phil Coulson, Lee Pace as Ronan the Accuser, Djimon Honsou as Korath, and Ben Mendelsohn and Lashana Lynch in undisclosed roles. The film is targeted for release on March 8, 2019.
