- An interview interview with bustle.com : Fares, who plays Antoine, is no stranger to the small screen, or the big screen, for that matter. He previously starred as Fauzi Nadal in the FX series Tyrant, and in the acclaimed film Zero Dark Thirty as CIA officer Hakim. But this new role, which sees Fares playing a character who does not seem to be defined in relation to the Middle East, is actually a departure for the actor. In an interview with The National, Fares, who is of Swedish and Lebanese descent, noted that often the roles he is offered reflect his Arabic roots. He said:'"A lot of roles that are coming my way are Middle Eastern and I really don’t have a problem with that as long as I’m are playing a person, not a cliché. I have always tried to mix it up. Interesting offers are coming from that part of the world — but I am not interested in playing bad guys."
