Extant Season 2: Who's In? Who's Out?

Extant Season 2 Cast

CBS’ Extant is readying some of its cast for blastoff.

Due in part to a shift in storyline focus for Season 2 — in which Halle Berry’s Molly will search for her alien offspring — original players Goran Visnjic and Camryn Manheim will only return for a couple episodes, our sister site Deadline reports, while Hiroyuki Sanada and Michael O’Neill won’t return at all.

So, who’s definitely on board for Season 2 of the of the summertime drama? In addition to series lead Berry, Pierce Gagnon (who plays Molly’s android son Ethan) and Grace Gummer (Humanichs partner Julie Gelineau) will return as series regulars, while a few new roles have yet to be cast.

Extant premiered in July to 9.6 million viewers and a 1.6 rating, but by its Sept. 17 finale had slipped to 5.4 mil/1.0. TVLine readers gave the season as a whole a grade of “C+.” It, along with Under the Dome, was granted a renewal in early October.
