The 'Behind Her Eyes' Cast: Your Complete Guide

Single mom Louise rolls into her first day of a new job only to discover that her new boss is the (married) man she hooked up with the night before. An auspicious start! Things only get worse from here, as she strikes up yet another ill-advised relationship with David's wife Adele.

Brown is a British actress with a practically spotless record when it comes to joining prestige TV adaptations of bestselling novels: She's starred in The Little Drummer Girl, The Night Manager, and The Casual Vacancy, and also had a guest role in Outlander in 2018. She also took on the lead role in Netflix's Kiss Me First the same year.

Of course, it takes two to tango—or, you know, to construct the facade of a seemingly perfect marriage—and Eve is just as full of secrets as her husband, many of which are explored bit by bit in flashbacks to her mysterious past.

Hewson, born Memphis Eve Sunny Day Hewson, is about as Irish as it gets: She was born and raised in Dublin, and her dad is Bono. Casual. Her feature film debut was in 2008's The 27 Club, and she has since starred in films including Bridge of Spies, Robin Hood, and Tesla.

Rob features heavily in the flashbacks into David and Adele's past, but seems to have come to a tragic end sometime between then and the present. Would it surprise you to learn that here, too, all is not as it seems?

Like the rest of the star-studded cast, Oxford-educated Aramayo has an impressive list of credits: You may recognize him from his roles in Nocturnal Animals, Mindhunter, or Antebellum, or from his arc as young Ned Stark in Game of Thrones. Next up, he'll appear as Beldor in the much-hyped Lord of the Rings series on Amazon Prime.

Adam is Louise's son and main priority, and just might be the only character in the show who's not hiding any life-or-death secrets. There had to be one!

He may have only started acting three years ago, but this isn't Howitt's first foray into high-profile TV: He previously appeared as Billy Costa in three episodes of HBO's His Dark Materials. His first role came in 2018, when he played Reggie in an episode of U.K. children's series Apple Tree House.

Sue works in David and Louise's office as a secretary. Fortunately for her, she successfully avoids getting swept up in their seemingly endless maze of drama. Way to stay above the office politics, Sue!

Scotland-born Glen has appeared in dozens upon dozens of films and TV shows since the mid-'90s, making the real question here where haven't you seen her before? Some of her most recent credits include The Crown, Call the Midwife, The Hitman's Bodyguard, and Jackie.
