Avengers Infinity War: ANOTHER big star added to huge cast – guess who?

The 37-year-old has filmed scenes with motion-capture playing part of Thanos’s deadly Black Order in the all-star Marvel caper.

She’s playing Proxima Midnight, as confirmed by co-director Joe Russo in a new video interview.

“Carrie Coon is Proxima Midnight,” he declared.

“You may know her from season three of Fargo or the Leftovers.”

Proxima Midnight is the only female member of the Black Order – and wields a great deal of power.

It’s been revealed that the stars voicing the other two Black Order members are Tom Vaughan-Lawlor as Ebony Maw and Terry Notary as Cull Obsidian.

“Well, he did voice the character, but he’s one of the most gifted movement specialists in the world right now,” Joe said of the latter.

“He played a character who we’ve called Cull Obsidian, who was in the books known as Black Dwarf.

“So it’s kind of an all-star cast of baddies.”

The directors have also spoken out coyly on rumours that Robert Downey Jr’s Iron Man will be exiting the franchise.

Avengers: Infinity War is out on April 25.
