Marvel Head of Television Jeph Loeb arrived to a packed room at Comic-Con International on Friday in order to discuss the latest Marvel TV updates, including their ABC shows "Agents of S.H.I.E.L.D." and "Agent Carter."

Loeb entered the stage wearing Agent Carter's signature red fedora, introducing the panel just as Hayley Atwell walked up behind him and took her hat back.

"This is really our way of saying thank you to everyone who's here," Loeb said as Atwell walked back off stage. He called for the "Agent Carter" fans to speak up, with a roar of approval from the audience, and did the same with "Agents of S.H.I.E.L.D." with a similar response.

To get things going, Loeb rolled some footage from the first season of "Agent Carter," which was spattered with furious applause from the audience at key moments and lines of dialogue.

As the footage drew to a close, Loeb announced that the music from "Agent Carter" and "Agents of S.H.I.E.L.D." will be released this fall.

"These shows are made with so much love," Loeb said, introducing Chris Dingess, Tara Butters and Michele Fazekas.

"The first time we were here as panelists were for 'Reaper,'" Fazekas shared.

"The real challenge of season one was finding an actor who existed in comics for a long time and at the same time existed as a voice and is now played by a different actor," Loeb said, introducing the character of Jarvis as James D'Arcy walked on stage. This is D'Arcy's first comic con.

"They took us through the back way and he said to me, 'This doesn't seem very crowded,'" Loeb shared.

"Yeah, I was wrong," D'Arcy admitted.

"It is our extraordinary pleasure every day to work with Hayley Atwell," Loeb said by way of reintroduction for Atwell as she rejoined him on stage.

"This is the one show that ABC makes with Marvel Studios," he explained, thanking Kevin Feige.

"I remember walking through the Marriott last year with you, telling Hayley, 'You'll never be able to do this again.' It really is amazing to walk around with her and everyone is excited and all the cosplay," Fazekas said.

"And I have to say the fan art," Butter added. "If you put it up for sale, I probably bought it."

"I'm really happy because we love it so much," Fazekas rejoined.

"It's the best job I've ever had," Butters pitched in.

"Me too!" Atwell cried.

"In the pilot, Jarvis is making souffle, and I can't actually make a souffle, and I was worried I was going to have to make a souffle... so my apprehension revolved around souffle making. I can do a great Spotted Dick... we had a long conversation about that, and then they explained to me what acting is," D'Arcy laughed. "The thing that really sold it to me was when Michele and Tara and Chris and Jeff said to me, 'Oh, he's going to be with her on the missions.' And I thought I was going to be doing some fighting, and they went, 'Well...'"

"I've never actually had an opportunity to do anything comedic on film before, so I wasn't sure if I could do it, but it just turns out that I had to just be myself and it would turn out just fine," he added.

"I think first of all the quality of the writing," Atwell remarked on what drew her to the role in the first place. "We'd seen aspects of Peggy in 'The First Avenger,' so I jumped at the chance to [play her again]. She's kind of taken over my life in amazing way. She's just fearless... she thrusts herself into situations with such wild abandonment, so I love that opportunity. It's changed my life."

"I just loved her and I really hoped that the writers would get her right. I was really adamant about that. I read the script and I came out and went, 'This is amazing!' I had nothing but compliments. We're working with such talented writers. It's like you turn up and read the lines, you don't have to add anything," Atwell explained.

"Our writers have just beautifully come up with words that I wouldn't dare to use," D'Arcy added, "They come up with some beautiful dialogue."

When asked about the last moment of the season finale, Atwell said, "I think it was absolutely the right decision. I think by the end of the season she had grown. It was a burial for her in a way. I think she was concerned that if it got in the wrong hands... I think it makes it all bittersweet and for a better story."

"We shot that on a bridge in New York City," Loeb added.

"One of the benefits of working with Marvel is that people want to work with Marvel," Fazekas said. "ILM was such fans of the material that... it's some of the best effects I'd ever seen."

"The amazing thing for us, when you're building a city, they have 30 years of sets to help make New York City come to life," Butters pitched in.

"She doesn't need praise from anyone else. She knows her destiny. It's been amazing to go to conventions to have little girls and little boys come up to me saying, 'I know my value too!' It gives Peggy really depth," Atwell shared.

"There's a wonderful scene that I love where Jarvis tells her that she can't run away from people who want to help you, and I think he saw her vulnerability," she added. "He's a gentle spirit tapping her on the shoulder telling her she's not alone. I think he has some wonderful lines too."

Dingness also pulled out the voice he used for the "Captain America" radio show that played in the background of that show.

"We are off to Hollywood," Butters said of season two. "It's 1947, about 6 months after the show ended. Things are different. People are in different positions, and not everyone is in New York anymore. There's some history that we're not quite sure. Some people aren't talking to each other. Then Peggy gets called into a murder in Los Angeles... that was the same year as the Black Dahlia, and that intrigued us."

"Jarvis is actually already there," Fazekas pitched in. "He's doing some contract work."

"Am I going to meet my wife finally?" D'Arcy inquired, to a nod from Fazekas.

"No plans for actual historical figures," Fazekas shared. "I would say that Peggy has sort of put Steve's memory to rest and she has a couple of new opportunities."

With that, Dingness, Buttes, Fazekas, D'Arcy and Atwell exited the stage to make way for the next segment. In the interim, the panel rolled some footage from the second season of "Agents of S.H.I.E.L.D."

Loeb walked back on stage with Clark Gregg for the "Agents of S.H.I.E.L.D." segment, with a fake hand in tow as a reference to the end of the last season where Coulson lost his hand to Terrigenesis.

Following the gag, Loeb also introduced Luke Mitchell, Henry Simmons, Nick Blood, Adrianne Palicki, Iain De Caestecker, Elizabeth Henstridge, Ming-Na Wen, Brett Dalton and Chloe Bennet.

"It's bloody scary," Mitchell said of joining the show. "Coming on, I kind of wanted to slip in unnoticed. I just wanted to work as hard as I could. Everyone made me feel really welcome from the start. It was amazing."

When asked who he was on the show, Simmons leaned forward, got close up to the mic and said, "I'm the guy who kills Gordon." The audience roared its approval.

"I wrapped shooting a movie that night, got a flight that night, got picked up and driven right to set and was put in makeup," Blood shared about his recruitment for "S.H.I.E.L.D."

"It's pretty awesome to play this character a huge comic book character," Palicki said. "There was a lot of pressure coming in. You guys have been very warm and inviting. Thank you! And these guys especially. You guys are like the family."

Loeb took a timeout and rolled the never-before-seen gag reel, which starred most of the cast present.

Loeb announced that the DVD and Blu Ray will be released on September 18.

"I loved Chloe Bennet from the first moment I met her," Gregg said. "She brought everything we needed to make this thing work... The people like Brett -- I love him. We're so lucky to have this cast."

"Our audition was together and we were at the bottom of the ocean. Our impressions were probably that we were emotional wrecks," Hestridge said of DeCaestecker.

"I think we were the only two people who could understand each other," DeCaestecker joked.

"We were stuck on a bus for months on end, and he was flexing his muscles all the time, so I had to help him flex," Wen said of Dalton, nodding at the two's relationship during the first season of the show.

Someone then yelled "Hail Hydra!" from the front of the room, causing Gregg to stand up immediately in indignation. Dalton also pointed out a sign that someone had brought with the same message.

When asked how he felt when it was revealed that Ward was Hydra, DeCaestecker was at a loss for words. "He still can't talk about it," Henstirdge said sympathetically.

When asked what he learned on set, Mitchell responded, "Chloe is crazy."

Gregg agreed. "Chloe is crazy and Elizabeth is clean."

"To stand on my toes when I'm with Adrianne," Blood added in response to the same

"I've learned to pronounce really long words that sound sciencey," Henstrige pitched in. "It's a British thing. It comes at birth."

"What we're most proud of on the show is that anyone can run S.H.I.E.L.D.," Gregg told an 8-year-old fan who wanted to be on the show. "I feel that someday, you could run S.H.I.E.L.D... As long as you stay away from Ward."

"Hey, there's space on my team too!" Dalton cried.

"A lot of the work was done for me by Jeff [Loeb], so it really comes down to them," DeCaestecker said of portraying Fitz's injury. "I did some research myself. For me, one of the most surprising things that happened to Fitz this season and we were mindful and tried to be respectful because it affects a lot of people... But what surprised me is that not once did my teammates get me a monkey."

Loeb then rolled a pre-recorded video from the writer's room featuring showrunners Jed Whedon and Maurissa Tanchoren, who joked that they had no ideas. Whedon drops the codename Quake in the video, which also reveals a stack of "Inhuman" books. They also dropped the name Zephyr One for the team's new airbus. As the two discussed the previously announced "Secret Warriors" storyline, Tripp made a cameo and asked to be brought back to the show.

Loeb also announced that Lash, an Inhuman character created by Charles Soule and Joe Maduiera, would be in the upcoming season.

The cast and crew of "Agent Carter" came back out to bid the audience farewell as the panel drew to a close.
