Agents of S.H.I.E.L.D. season 2 is set to return to ABC on September 23rd at 9/8C. The Hollywood Reporter stated that Hayley Atwell, who plays Agent Peggy Carter, and George Stephanopoulos (Good Morning America, House of Cards), p[laying himself, will be appearing in the season premiere of the show.

cool.

Haley Atwel.................... I'd love that............. She's really pretty. :)

Y'know what I just realized? The "Agent Carter" series will probably let the audience know about how Hydra is growing within S.H.I.E.L.D., meaning the show will have more foreshadowing for that twist than Marvel actually put before it.

Reed Diamond!

Nice

I'm confused. Wasn't she an old bird in Cap 2? I'm going to assume the season is starting with a flashback or something. I can't remember who played her in Cap 2, but I'd rather see Sharon Carter in AOS. This isn't a knock on Atwell, I'm definitely going to check out the Agent Carter show.

I'm hyped for season 2!

Atwell played Peggy Carter in Cap 2.

Wait..she's getting her own show? Wow, Marvel really has some serious guts to be making just about anything they can think of right now. What are they rejecting?

Her getting a show is such old news, how haven't you heard of it?

@matthewparker: Yeah, but she was about 80 years old with Alzheimer's in Cap 2.

ohh, i think i misread your post, lol. if you're asking who played Sharon carter it was Emily VanCamp

Oh yeah, sophomore season is gonna be the Empire of the series. Darker, more characters, possibly droids.

Just picked up Season One today, I am totally not going to slow-mow the Skye-running-in-a-red-dress scene, no, not at all.

Hayley is a talent and a true dame. The only reason they're producing Agent Carter is because of her performance in the One-Shot video, as seen on the back of Iron Man 3. There is also an interview video from SDCC this year, with Hayley ... I got lost in her eyes.

I'm excited for the second season! The first season improved as it went along.

Here's hoping the show rebounds in the second season the same way Arrow did. I really have this feeling like the show could be on thin ice considering the high expectations it had. So they really need to pull out all the stops.

Hope that the second season keep improving.

Um...maybe everyone doesn't know everything all the time?

Nice update. Howling Commandos! Love the new 'do on Agent Carter.
