One revelation executive producer Howard Gordon shared is that part of the new season was shot in Israel but will be set in Beirut.

"We had a real kind of cultural exchange," Howard told fans. "We had a terrific time. Actually, the technical level there is quite astounding. They're experiencing a renaissance in television and film."

Shooting in Israel had it challenges as well, Howard said.

"In certain locations, people weren't that happy that we were there," he said. "It's charged. The atmosphere is charged and you'll see some of that tension translated in some of the film we got."

The trailer teased tidbits about fallen CIA analyst Carrie Mathison's (Claire Danes) future, one that involves a secret mission in Beirut. She'll also still be battling demons from her past, replaying her regrets and memories of Nicholas Brody (Damian Lewis) in her mind, and trying to move forward despite her severe bipolar disorder.

"How do you (deal with) essentially what is the most interesting part of that character?" Howard asked. "Carrie's mental illness is something you have to be mindful of and at the same time can't be crippled by. We're very mindful. That danger and that gift are always a part of that character."

Something Howard and his co-producer Alex Gansa have to be mindful of in real life is Danes' pregnancy, which will not be written into the show, he said.

"Homeland" returns for a second season Sunday, Sept. 30. at 10 p.m. ET/PT on Showtime.
