"The Killing" season 4 spoilers might not offer more details but the showrunner and cast provided the broadstrokes of what's to expect when the series airs in August. The final season is reportedly going to be "darker" compared to the previous three seasons.

Sterling Beaumon dished out "The Killing" season 4 spoilers when he told Varietythat the fourth installment is going to be "darker than it's ever been."

In an interview with the publication, the cast weighed in on the advantage of streaming the show online over at Netflix rather than showing it on TV, because it's not bounded by the limits of censorship.

As cast Gregg Henry said, "There's the old swearing thing and things like that."

His co-star Levi Meaden said that Netflix is changing the landscape of television by changing the way writers are allowed to tell a story.

He also dished out "The Killing" season 4 spoilers when he said that the swearing and violence don't "become gratuitous," even if it's shown online.

"But I think you can kind of prod at the darker parts involved in the murders a lot more," he said.

Netflix released official "The Killing" season 4 spoilers through its synopsis:

"The fourth and final season of 'The Killing' picks up right after the season 3 finale. As Detective Linden (Mireille Enos) and Detective Holder (Joel Kinnaman) struggle to manage the fallout from their rash actions at the end of last season, they are assigned a new case - a picture perfect family is murdered, survived only by the son, Kyle Stansbury (Tyler Ross), who was shot in the head during the massacre. Joan Allen guest stars this season as Colonel Margaret Rayne, the headmaster of the all-boys military academy where Kyle attends. The new season also stars Gregg Henry, Sterling Beaumon and Levi Meaden."
