'Family Guy' Producer Reveals Details About Carrie Fisher's Upcoming Final Episodes

Fans around the globe are still mourning the loss of Star Wars icon Carrie Fisher, who tragically passed away last December at the age of 60. Her legacy continues to live on however, and the beloved actress still has a couple of projects that have yet to air.

In addition to her role in Star Wars: The Last Jedi, which is set to hit theaters on December 15, Fisher still has two appearances left on the hit animated sitcom, Family Guy.

Over the years, Fisher voiced Angela on the series, Peter Griffin's boss at the brewery. She's appeared in over two-dozen episodes since 2005, with two more set to air this winter.

This Sunday's Family Guy will feature Fisher, as well as the late Adam West, and exectuvie producer Steve Callaghan talked with EW about the episode. First, he was asked about his reaction to learning Fisher had passed last year.

"It was stunning," Callaghan admitted. "Really devastating, and obviously very unexpected. My recollection is that she recorded for the show very recently, so it really came out of nowhere for us, and it was very, very sad. We couldn't believe it. Even now, it's hard to just really take in the truth of the situation that she's not part of the show anymore, so it's very upsetting for all of us."

The producer went on to talk about the loss of Fisher, along with Adam West, in terms of their roles on the show.

"It was incredibly difficult," Callaghan said of losing both icons. "The loss of each of those characters in itself was an enormous blow. And then to have two of them happen so close together — we've been able to absorb the loss in the show, but I think we're still processing emotions about losing these two actors from our lives."

In Sunday's episode, Angela gets the opportunity to fire Peter three different times. Once in the style of Quentin Tarantino, once in the style of Wes Anderson and once in the style of Michael Bay.

"First of all, I love the way that she delivers the lines in which she fires Peter in the style of Wes Anderson because she nailed, in my opinion, what those movies are and the acting styles that's contained within them," explained the producer. "I love Wes Anderson movies, but even he would admit that sometimes his characters speak in ways that are not like humans speak. She comes in dressed in this odd get-up that we've never seen her wear before, and says, 'You're relieved of your position.' It's like, who fires someone that way? Beyond just the words themselves, her delivery of it was perfect, just the right balance of realistic, but stilted and oddly distant.

"But I think probably my favorite version of her firing Peter is the Michael Bay [segment], which culminates with Angela and Peter engaging in the grossest, longest French kiss you've ever seen. [Laughs] So having to direct her to make those noises was hilarious. We were all just cracking up, because I remember saying to her, 'Okay, so now Angela is kissing Peter, and it's just wet and lots of tongue,' and she just jumped right into these ridiculously gross but hilarious noises. And it just went on for awhile, but we kept laughing with each new iteration of it. It was actually a lot of fun sorting through those different Carrie Fisher noises and figuring out which would be just the right level of saliva and grossness."

After revealing that Fisher will also appear in the December 10 Christmas episode, Callaghan went on to say just how the show plans on paying tribute to the late actress.

"I'm not going to say too much about that, but we do have an upcoming episode [airing next fall] where we deal with Angela's departure. The way we've written it, and the way that our characters on the show are talking about Angela, it's very much intended and a respectful goodbye to both the character of Angela and also Carrie Fisher. Peter has a speech in there where he's talking about Angela, but we the audience know that he's also quite deliberately talking about Carrie Fisher. It's not like the entire episode is about Angela's departure, but it does introduce Peter's new bosses that then sets the stage for what the episode is about. Her departure is an integral part of it, but that's not the story of the episode."

Family Guy airs on Sunday nights at 9 p.m. ET on Fox.
