Big Sky is adding some new faces to its second season.

The show is set to return this autumn on ABC in the US and Star on Disney+ as it moves beyond the kidnapping mystery on a Montana highway.

According to Deadline, several new cast members have joined Big Little Lies boss David E Kelley's latest TV drama series – including The Sopranos' Jamie-Lynn Sigler as a diner waitress whose boyfriend disappears without a trace.

What to Read Next

It is Sigler's character Tonya that kicks off the season's story by hiring Dewell (Kylie Bunbury) and Hoyt (Katheryn Winnick) to find her partner while withholding some damaging info.

The Walking Dead: World Beyond's Madelyn Kientz joins the show as Dewell's teenage babysitter Max, while Troy Johnson of Netflix's On My Block portrays Max's opportunistic best friend Harper.

Also joining the new season 2 cast are Barkskins actress Lola Reid as Max and Harper's pal Madison, It's Ray Taylor as Madison's older brother Bridger and Limitless's TV Carpio as Max's mum Rachel.

Rounding off the new cast members will be Fear the Walking Dead's Arturo Del Puerto, playing Rachel's sleazy boyfriend T-Lock. He can get the whole family in trouble with his get-rich-quick schemes.

All of these new Big Sky cast additions are needed because it was recently confirmed that the show will be losing some major players ahead of season two.
