If this had a remake
Let's hope it won't happen but being honest I wouldn't be surprised it its remade, so if it had to
I'd cast
Eva Green or Natalie Portman as Hanna
Antonio Banderas would be Kip
Michael Fassbender Caravaggio
Christian Bale or Henry Cavil Almasy
Katherine Cate Beckinsale, Charlize Theron or Rachel McAdams
Geoffrey Daniel Craig
