Specualating the roles of new cast members
Rami Malek - Confirmed to be the main villain
Lashanna Lynch - I saw a video of her with Naomie Harris in London inside the MI6 HQ set and it looks like she'll be an MI6 agent.
Ana deArmas - We know that her character name is Paloma but I'm guessing she'll be some sacrificial lamb or a femme fatale
Billy Magnussen - When his name was being considered it was said he would play a CIA agent, but I wouldn't surprised if he's playing some bureaucrat who's giving Felix some trouble.
Dali Bensalah - I could see him as a henchman
David Dencik - Confirmed to be playing a villain named Waldo
