It’s double the trouble for Michelle Monaghan (True Detective), as she’s been cast to star as twins in the upcoming limited series, Echoes, at Netflix. Monaghan’s casting was announced on Thursday morning, following Netflix giving Echoes a straight-to-series order last month, as reported by The Hollywood Reporter. 

Monaghan is set to play twin sisters, Leni and Gina, in the seven-part series. According to The Hollywood Reporter, Echoes is: “A mystery thriller about two identical twins, Leni and Gina, who share a dangerous secret. Since they were children, Leni and Gina have secretly swapped lives, culminating in a double life as adults: they share two homes, two husbands, and a child but everything in their perfectly choreographed world is thrown into disarray when one of the sisters goes missing.” 

Stepping into both pairs of shoes, Monaghan has her work cut out for her as the twins could not be anymore different. Leni is described as the calmer of the two, and okay with playing it safe. She’s married to her childhood sweetheart, and together they’re content to live a quiet and peaceful life while raising their daughter on their horse farm. 

Geni, on the other hand, is the wild card. Wanting something much different for herself, she left her sister behind and ran away to Los Angeles to fulfill her dreams. There, she became a famous author as she wrote about her southern upbringing, and the darkness that lay beneath the pretty farmland. 

This marks Monaghan’s second project at Netflix. She starred in the Netflix original thriller series Messiah, which ran for one season before it got cancelled. Monaghan also had a leading role in the Hulu drama series The Path, which ran for three seasons from 2016-2019. Her most acclaimed television role came in 2014 when she starred alongside Woody Harrelson (Zombieland) and Matthew McConaughey (Dallas Buyers Club) in the first season of True Detective on HBO. Her film credits include starring roles in Gone Baby Gone, Mission Impossible: Ghost Protocol, The Best of Me, Patriots Day and The Craft: Legacy. 

Vanessa Gazy (Eden), Quinton Peeples (Runaways), and Brian Yorkey (13 Reasons Why) will executive produce. In addition, Peeples and Yorker will serve as the series showrunners. Notably, this is the first project Yorkey has brought to Netflix since his overall deal with the streamer after his helming of the breakout series 13 Reasons Why.
