It's no secret that most actors are instructed to keep details of their shows under wraps, but "Mad Men" creator Matthew Weiner runs an especially tight-lipped ship.

In an interview with the LA Times, Ben Feldman -- who plays newcomer Michael Ginsberg -- admitted Weiner has everyone sworn to secrecy, and may even have them teasing false storylines.

"I know nothing about the sixth season," Feldman said. "Whether you’re never going to see me again on the show or whether 'Mad Men' will be a one-man show starring Ben Feldman is nothing I could ever speak of ... you feel like you’re a member of Seal Team Six when you’re shooting."

Similarly, in a video interview with Details magazine, Vincent Kartheiser (who plays Pete Campbell) emphasized his lack of knowledge on Season 6 of the series.

"You never know which characters are or aren't going to come back, you never know where you're gonna be, you never know what year it's going to be," he said. "We know as much as everyone else, which is absolutely nothing. And to be honest, I like it that way!"

What do you think about Weiner's decision to keep the details of "Mad Men" a secret? Sound off in the comments.
