For All Mankind season 5’s latest casting announcement is giving me a Joel Kinnaman reunion I’ve been waiting a decade for. After an incredible fourth season, I was thrilled to learn that AppleTV+ hadn’t just commissioned For All Mankind season 5, but a spinoff series that tells the story from a Soviet perspective. While the specifics of the Star City spinoff are still vague, For All Mankind‘s recent casting announcement heavily implies that it’s full steam ahead for season 5, potentially aiming for a 2025 release date.

The huge time jumps between seasons of For All Mankind necessitate a constant influx of new characters, and season 5 is no exception. A report in Variety confirmed that Mireille Enos will join For All Mankind season 5 as new series regular, Celia Boyd. Enos’ character is described as “a member of the Peacekeeper Security Force on Mars,” which places Celia Boyd in the path of Old Man Mars himself, Ed Baldwin. This is particularly exciting for me, and fans of The Killing, because it reunites the show’s two lead actors.

For All Mankind Season 5 Is Reuniting The Killing’s Joel Kinnaman & Mireille Enos

Of course, For All Mankind season 5 won’t be the first time that Joel Kinnaman and Mireille Enos have worked together since The Killing ended in 2014. Kinnaman and Enos were previously reunited for the Prime adaptation of Joel Wright’s movie Hanna, but their reunion was disappointing. Their antagonistic dynamic was in sharp contrast to their collaborative characters in AMC’s adaptation of The Killing, who made a compelling detective duo. While I’d always been a bigger fan of the Danish original, the performances of Mireille Enos as Detective Sarah Linden and Joel Kinnaman as Detective Stephen Holder sold me on the remake’s merits.

I’m therefore hoping that Joel Kinnaman and Mireille Enos’ relationship in For All Mankind season 5 will be more cooperative, and that they’ll share more screen time than in Hanna. However, given that Ed Baldwin led an asteroid heist from the Happy Valley colony on Mars, it’s entirely possible that his relationship with Enos’ Celia Boyd will be antagonistic. However, whether Ed Baldwin and Celia Boyd’s relationship is positive or negative, I’m still excited to see Joel Kinnaman reunited with his The Killing co-star in For All Mankind season 5.

Why Mireille Enos’ For All Mankind Role Is Great For The Show’s Future

As much as I love Joel Kinnaman as Ed Baldwin, it’s fair to say that the character doesn’t have much mileage left in him. Ed will be 81 in For All Mankind season 5, meaning that Joel Kinnaman will have to wear more layers of prosthetics to “age up”. And while 81 may be a suitable age to be leader of the free world, it likely discounts Ed from continuing to be an astronaut on Mars. This makes me concerned about Ed Baldwin’s fate. However, the introduction of Mireille Enos as Celia Boyd gives For All Mankind the scope to give us new characters to love, who are at the forefront of the next generation of space exploration.

For example, I loved Toby Kebbell’s character, Miles Dale, in For All Mankind season 4, and certainly hope that he too will be back, leading the civilian workforce on Mars. Similarly, Coral Peña and Cynthy Wu were exceptional as Aleida Rosales and Kelly Baldwin, and I’m really excited to see where their characters go in season 5. Adding Mirielle Enos into the mix means that, while Ed Baldwin, Dani Poole and Margo Madison’s time may be limited, the future of For All Mankind is in very safe hands.
