For All Mankind Season 4 Release Date, Cast, Plot, Trailer And More Details

While the majority of the "For All Mankind" cast was present at the renewal announcement for Season 4, the Season 3 finale episode revealed that some of the cast's time on the show has already come to a close. As it stands, Joel Kinnaman will return as series lead Ed Baldwin, as will Wrenn Schmidt as Margo Madison, Krys Marshall as Danielle Poole, Cynthy Wu as Kelly Baldwin, Casey W. Johnson as Danny Stevens, Edi Gathegi as Dev Avesa, and Coral Peña as Aleida Rosales. TVLine reported in August 2023 that Jodi Balfour will no longer be a series regular and her time on the show will most likely come to an end, with her character arc as President Ellen Waverly probably wrapping up in Season 4.

And as "For All Mankind" Season 4 covers a new era, there's a need for new characters and new actors. Toby Kebbell of the Apple TV+ show "Servant" will join as Miles, an oil worker who quits his job to take a new one on Mars. Tyner Rushing, a standout in "The Terminal List," will also be a series regular. We'll also see Maria Mashkova of "McMafia" as a co-pilot, Salvador Chacon ("Mayans M.C.) as Gerardo, Miles' roommate on Mars, Svetlana Efremova ("The Americans") as a Soviet official, and Dimiter Marinov ("Green Book") as a veteran of Mars. Daniel Stern, famous for "Home Alone" and "Shrill," will take a major role as Eli Hobson, a brand new and powerful NASA administrator.
