Hulu is getting serious with “Casual,” renewing the family dramedy and upping the episode order to 13 for season two.

The Los Angeles-set series stars Michaela Watkins and Tommy Dewey as romantically-challenged siblings who are cohabiting and learning to come to terms with their lives. The series also stars Tara Lynne Barr as Watkins’ daughter, Laura, and Nyasha Hatendi as Dewey’s oft-begrudged friend, Leon.

“‘Casual’ really struck a chord,” said Craig Erwich, Hulu’s senior VP and head of content. “We couldn’t be prouder of the quality, and we’re thrilled to see it be recognized for the success that it is.”

The series is created by Zander Lehmann and hails from Jason Reitman and Helen Estabrook’s Right of Way Films in association with Lionsgate. The three exec produce along with Liz Tigelaar.

“We are thrilled that viewers immediately embraced this smart, dysfunctional family comedy, brought to life through Zander Lehmann’s distinct, inventive voice and vision of executive producers Jason Reitman, Helen Estabrook and Liz Tigelaar,” said Kevin Beggs, chairman of Lionsgate Television Group. “Hulu is a great partner and the perfect home for this series. We look forward to where they take these characters and storylines in season two.”

The 10-episode first season of “Casual” airs Wednesdays on Hulu.
