Celebrating its return to AMC for its second season, premiering April 1, the cast and producer of "The Killing" assembled at the Arclight Cinema in Hollywood for a red carpet screening, where they shared insights into the deepening murder mystery and their favorite ways to live a little greener. On set, "The studio is very committed and very eco-friendly so there's no use of plastic bottles. We have coolers that get schlepped all over the place," said producer/writer Veena Sud, noting that shooting in eco-friendly Vancouver makes it easier to implement green practices. "The Canadians are leaders in that."


Season one's finale upset some viewers when it didn't reveal the killer in the case of murdered teen Rosie Larsen, but Sud reminds that the series, which is based on the Danish drama "Forbrydelson," was always intended as a two-season story arc, although now "we're going in a very different direction, including who Rosie's killer was. There is so much more to be uncovered, so much more to learn about everyone, about the cops, about the politicians, about the family," she added. "Season one was about asking questions. Season two is about answers to those questions."


As detective Sarah Linden, Mireille Enos earned an Emmy nomination for her role in the also-nominated series. "I love that she's multi-dimensional. She's fallible. She's not always very nice to be around. Women are usually the good girl or the horrible b*tch — it's just so rare to find someone that's just human," said Enos, who has two very different roles coming up: she'll play the wife of the cop (James Brolin) who took down L.A. mobster Mickey Cohen (Sean Penn) in the '40s in "The Gangster Squad," due in October, and she stars opposite Brad Pitt in the summer 2013 zombie pandemic flick "World War Z." "One of the storylines is a family trying to survive and I play the mom." The mother of an 18-month-old daughter in real life, she's especially eco-conscious of her home environment. "My baby sleeps on an organic mattress, wears organic cotton, we feed her organic food," she said.


Joel Kinnaman, who plays Linden's partner Stephen Holder, shockingly revealed to have faked important evidence in the investigation, promised more surprises to come. "We're going to see a little more of Holder's back story. We're going to meet his family, his sister and nephew, who come into play, and it's going to be heart wrenching," said Kinnaman, who loves sinking his teeth into this character with a dark, drug-addicted past. "He's made a couple of bad choices in his life, but that's one of my favorite things about the show. It takes place in a gray zone, and forces the viewer to take stand from a moral standpoint. Do I like this person? Can I accept his actions? It's not black and white."


Accustomed to taking public transportation in his native Sweden, Kinnaman finds it "more difficult to be environmental in the states. We're always driving here. There's more infrastructure in Sweden," he compared, noting that he recycles nevertheless. He's been cast in the title role in the new version of "Robocop," which he calls "a reimagination" with "a couple of throwbacks to the original. I'm super-stoked."


Held at gunpoint when we last saw him, Billy Campbell's city council president and mayoral candidate Darren Richmond deals with the cataclysmic aftermath in the season premiere. "As intense as the first season was, this season is that much more intense. It blows me away every week. It keeps us excited and that keeps the audience excited." Campbell used his hiatus to make a couple of films, playing the father of the titular character in "Fat Kid Rules the World," directed by actor Matthew Lillard, and "The Disappeared," a drama about six men lost at sea shot last summer in Lunenberg, Nova Scotia, where avid sailor Campbell is building a schooner that he plans to sail to the South Pacific. "We're building the old fashioned way, which means there's not a lot of plasticene or resins or any of that stuff. It's old school. Wood is a renewable resource. Wooden schooners are naturally green."


Brent Sexton, who drove a rented Prius during "The Killing's" first season and recycles at home, compares his character Stan Larsen, the victim's father, to an oak tree. "He's a solid, nice guy and he works hard, he's built an incredible life that he loves, and when it starts to crumble and things are going away he really just wants to hang on." That causes him to make some fateful moves, getting involved with his old cohorts in the Polish mafia. "Can you outrun your past? Stan made some decisions when he was younger that might come back to haunt him. It's the past, the present and the future all at once and you can't get resolution in one area without consequence in another area."


"Everyone is going to be paying a price for secrets that they've kept, and there's going to be answers to all the questions that everyone had," said Jamie Anne Allman, who plays Stan's sister-in-law/sometime-prostitute Terry. Next seen as a drug addict in the feature "Any Day Now" opposite Alan Cumming and Garrett Dillahunt, Allman recycles and uses chemical free, natural skin care products from Epicurean and makeup from Youngblood. She's been a vegetarian for nearly four years, prompted by caring for her cancer-stricken grandmother and becoming convinced of the necessity of a healthier diet. "But I now know about the treatment of animals and all that," she added.


Mark Moses joins "The Killing" this season as the new police chief, who may have some secrets of his own. "I come in to straighten out the investigation," said the actor known for his roles in "Mad Men" and "Desperate Housewives." "It's great to do this dark show about a murder mystery," he said, noting that he was a fan of both Season One and the original Danish version. "The show unfolds slowly, it doesn't wrap up in one hour. I love that it's different from so many police dramas," said the actor, who recycles and drives a Prius. He'll be seen on the big screen opposite Steve Carell in the comedy "Seeking a Friend at the End of the World."


"I love that he doesn't necessarily show everything and he's always a couple of steps ahead. He's very smart. He's very driven. He's very loyal. He's manipulative but only when he needs to be," said Eric Ladin of his character, Richmond's campaign manager Jamie Wright. "This season you'll find out why he is the way he is. History and relationships are revealed." Coincidentally, he and Michelle Forbes, who plays Mitch Larsen, made a film together pre-"Killing" called "Highland Park," about what happens to a group of lottery winners after hitting it big. "I play a school bus driver, divorced with two little kids, and Michelle is the wife of Billy Burke, who plays the school principal," explained Ladin, a Prius driver and diligent recycler who's looking into getting solar panels for his roof.


Kristin Lehman, who plays Richmond's advisor and lover Gwen Eaton, praises her character's persistence and strength. "She has a perseverance that I don't know that I have," mused the actress, excited about the forthcoming "really rich, really ambitious" season. Proudly describing herself as "very green," she's a member of the environmental committee at her son's pre-school, where the kids bring their lunches in reusable containers, food waste is composted for the school garden, and other waste is recycled. "We put big, mature snake plants in the classrooms because they clean the air of pollutants," she said. At home, she uses toxin-free cleaning products, grows tomatoes, peppers, herbs, and strawberries in a container garden, and recycles everything, with the help of her four-year-old boy. "We also recycle clothes. I pass down his clothes to other kids, and I buy a lot of vintage," she added.
