Infos von der Comic-Con (evtl Mini-Spoiler):
Season 2 is going to be 10 episodes long.
The show will be based out of 1947 Hollywood for the duration of Season 2. It takes place about 6 months after the end of the previous season, so there will be a little bit of a time jump. Relationships and positions are going to be a little different. Agent Carter is being sent out there to help investigate a murder.
When asked the showrunners said that the show won’t have many historical people, but as Los Angeles still has a lot of locations that haven’t changed much since the 40s they plan on filming a lot of iconic Los Angeles locations.
