Being a part of the Marvel Cinematic Universe is a pretty big deal. Almost everyone who is involved in one brings something unique to the roles they play. Tom Hiddleston did it for Thor and The Avengers, and Hugo Weaving – despite what he may have said about returning to reprise his role – did it for Captain America: The First Avenger.

With Ben Kingsley taking on the villain role for Iron Man 3 (check out the new trailer here), and Christopher Eccleston playing the villain in Thor: The Dark World, a new actor has emerged to possibly face off against Cap in Captain America: The Winter Soldier. Except, he might not play as the titular villain. Check out who he might play below.

According to a couple of twitter updates, Frank Grillo (The Grey, Warrior) has been testing for the role of Crossbones. While the tweet – which has since been deleted – doesn’t mention the role specifically, Grillo mentioned something to the extent of Captain America.

However, IGN UK did some digging and found out that Grillo was testing for the role of Crossbones.

For those who are unfamiliar with the character, Crossbones started out as a mercenary, who enlisted in a new army led by the Red Skull – who led under the alias Albert Malik. According to the wikipedia page, Crossbones is a master hand-to-hand combatant and expert marksman and pilot. The assassin did have a vital role in the Civil War storyline, which involved the Falcon and the Winter Soldier, so that could tell us what Marvel Studios is planning for Phase 2.

The first portion of that description might be a little difficult given what Hugo Weaving has said about reprising his role, but it will still be interesting to see how directors Anthony and Joe Russo introduce this character into the film. There is a slight possibility that Toby Jones could reprise his role as Arnim Zola – in the comics Zola was able to transfer his consciousness into a cybernetic being – but that is just speculation.

Chris Evans, Anthony Mackie, and more star in Captain America: The Winter Soldier. The film opens in theaters on April 4, 2014.
