Marvel's 
The Eternals has found its Ikaris in the form of Richard Madden.
As first revealed by The Wrap, the former 
Game of Thrones alum is in negotiations to join 
Angelina Jolie and 
Kumail Nanjiani in the Marvel Studios cosmic adventure, which will be directed by 
The Rider's Chloe Zhao. Though this initial report didn't name the character he'll be playing, 
Variety has since chimed in and confirmed that he has indeed been cast as the virtually immortal Ikaris.
Madden is best known for his portrayal of the doomed Robb Stark during the first three seasons of 
Game of Thrones, but more recently he garnered high praise for his turn in BBC drama 
Bodyguard.
The Eternals hasn't been given an official release date just yet, but it is expected to commence production later this year.
