The Diplomat cast

Netflix's latest politically charged drama The Diplomat has hit the streaming service and fans are already obsessed with the show and its star-studded cast. 

Netflix is on a roll, dropping new hit shows and films like the steamy Obsession, who's ending needed a little bit of explaining, and the heartbreaking film 2 Hearts inspired by the real-life story of Jorge Bacardi and Christopher Gregory. And they're not slowing down. Netflix's latest offering, The Diplomat, has viewers in a frenzy and they're desperate to know more about the show and its cast. 

The Diplomat follows Kate Wyler as she navigates her new role as the US ambassador to the UK, a job she did not want. Despite this, viewers watch as Wyler is plunged into the job, working hard to quash the growing possibility of a war between the UK and Iran, which could very easily become a worldwide war - something the US understandably does not want to happen. 

Kate attempts to uncover secret plots, and hidden motivations to get to the bottom of what she suspects to be faulty intelligence and reckless diplomatic behavior. While all of this was going on, many viewers couldn't help but continually wonder where they had seen the members of this large and star-studded cast before; their faces and voices felt very familiar but hard to place. Here we break down exactly who the cast of Netflix's The Diplomat actually are...
