The CBS summer mini-series "Extant" is returning to primetime TV with Season 2, but the show will be bringing in new characters and phasing out others. The show is expected to be a revamp of some of its characters and story.

The news of the show's new look was delivered this week. Oscar winner and star of the show Halle Berry will be staying on, but two Emmy winners will be phased out after a few episodes.

Berry will be earth-bound in Season 2 of "Extant." She will return as Molly Woods, the International Space Exploration Agency (ISEA) astronaut, and she will be joined by her android son Ethan, played by Pierce Gagnon. Also coming back to kick alien butt is Julie, played by Grace Gummer, Deadline reported.

Goran Visnjic, who plays Dr. Woods, the engineering scientist and husband to Molly who designed and built Ethan, will be leaving after a few episodes in the second season. Visnjic's character was a series regular in the first season. And, Camryn Manheim, who plays Dr. Sam Barton of the ISEA and is Molly's friend, will also be out after a few episodes, according to Deadline. 

Visnjic is an Emmy-nominated actor and Manheim is a Golden Globe- and Emmy award-winner.

Hiroyuki Sanada and Michael O'Neil will not be coming back in Season 2. While Manheim, Visnjic, Sanada and O'Neil will be out, the show will be bringing in new characters to fit into the newer storyline, Deadline reported.

The show's first season followed Molly, the ISEA astronaut, who returned back to Earth after a 13-month solo space mission. Molly joined her husband, Dr. Woods, and her robot son, Ethan. The surprise was that Molly had returned home pregnant with a space baby, CinemaBlend reported. Molly had to fight and successfully stop alien spores from landing on Earth that would eventually take over the human race.

The Season 1 finale left off with Molly's alien baby getting picked up by strangers on the highway while Ethan had sacrificed his physical form by uploading his consciousness onto the internet, CinemaBlend reported.

The story is expected to focus on Molly as she tries to track her down her alien son who is threatening the human race, iO9 reported.

The revamp sounds necessary for the show, although "Extant" did exceptionally well in its 13-episode summer run. During the summer of 2014, the show averaged 8.64 million viewers, and 1.7 in adults within the 18-49 age group. And the show did great business in DVR and online viewing in the U.S., as well as internationally, Deadline reported.
