The little alternate-timeline-show-that-could is back for a fourth season. In For All Mankind Season 4 we’ve jumped ahead to an alternate 2003, in which the Mars Happy Valley Base from Season 3 is now firmly established. But, for those who have been watching the show since Season 1 — which was set in 1969 and 1973 — perhaps the most obvious difference between then and now is we’re down to just a handful of original cast members. Because 34 years have passed in the fictional timeline of the show, mainstay characters Ed Baldwin (Joel Kinnaman), Danielle Poole (Krys Marshall), and Margo Madison (Wrenn Schmidt) are now borderline senior citizens.
