Get Ready, Fans! 'iZombie' Season 4 Is 'Different in All the Right Ways'

When “iZombie” returns Monday for the Season 4 premiere… it's going to be a very different show.

As fans know, Season 3 went out with a bang as the world learned that zombies exist. Seattle – aka zombie central – has been cut off from the outside world, and Fillmore-Graves announced a plan to keep the undead in check.

ExtraTV.com was invited to the set in Vancouver where the cast opened up to reporters about what to expect.

Rose McIver, who plays Liv, insists “it's different in all the right ways,” adding that fans can still rely on the cases of the week, the show's signature humor and the “relationship stuff,” but there is a lot more at play.

Something Liv is really struggling with is the politics of it all. “What we look at in this season is there's all sorts of people sitting on all sides of the fence, like we have coyotes that believe in smuggling humans in to turn them into zombies, we have Fillmore-Graves, [who have a] 'We run the show kind of approach,' we have a zombie church… very devout followers who take things very dogmatically.”

Liv's on-again/off-again boyfriend Major is more entrenched in the new world with his job at Fillmore-Graves.

Robert Buckley opened up about his character, saying, “This year we're seeing him rise in rank a bit… he has his own unit. And in addition to that, he kind of gets closer with [the boss] Chase Graves. So we start to see an unlikely relationship start there.”

Major will also get back to helping at-risk youth, something Robert says Major is very enthusiastic about and sees as his “calling.”

It doesn't sound like the turmoil is helping Liv and Major's relationship. Rose put it this way, “Liv and Major still have a deep fondness for each other, but definitely politics get in the way for them this year.”

Liv will still be eating brains – and taking on some wild new personas – while working closely with her detective partner Clive (Malcolm Goodwin) and Medical Examiner Ravi (Rahul Kohli).

Malcolm revealed that in this new Seattle every detective is paired with a zombie. Seattle PD handles human on human crimes and Fillmore-Graves handles zombie on zombie crimes. “You do have those scenarios when it crosses paths where a zombie may kill a human a human may kill a zombie,” and that gray can lead to problems as they try to figure out who handles those cases.

On a personal level, Clive is dealing with a problematic situation with girlfriend Bozzio. “The love of his life is now a zombie and he's just exploring the difficulty of trying to make that relationship work,” Goodwin said.

Meanwhile, fans want to know if Ravi is going to be a zombie next season. Kohli wouldn't say, only teasing that fans will know “within the first act” whether Ravi is a zombie and the answer isn't “black and white.”

We do know that the M.E.'s search for a zombie cure “intensified and magnified” this season.

Then there is Blaine, who David Anders says is purely focused on money, power, and greed this season. He turned his Shady Plots funeral home into a restaurant for zombies, and fittingly named it Romero's.

Anders says it is “cemetery to table” and described it as “a fine dining establishment for the one percent zombies.”

He's also battling daddy issues after his father Angus escapes the well he was trapped in and starts the zombie church mentioned above. David says that Angus “accrues this huge following of zombies that become somewhat of an army.”
