Now that Season 4 of "American Horror Story" has made its freaky debut, creator Ryan Murphy is teasing some details about "Freak Show's" cast, twists and upcoming guests.

Jessica Lange has previously stated that "Freak Show" will be her last season on the FX series. In an interview with hypable, however, Murphy said that Lange has been "reinvigorated" by her role as Elsa, her favorite yet.

"Before I was met with a really quick no and now I'm hearing, 'Let's keep talking,'" Murphy said. "So that's a promising sign. ... I think if I presented her with the right character, it could work. That's my hope. I'm sending bribes every day!"

Murphy dished that the truth behind Elsa's legs will eventually be revealed (and no, it has nothing to do with the war).

One episode this season will feature "White Collar" actor Matt Bomer. Murphy is already planning on inviting Bomer back for a future season.

"He likes to do the opposite of what he has done," Murphy said. "It's a true horror scene. He'd never played anyone like this before, and I know he really enjoyed being on the set with those actors."

In addition, former "How I Met Your Mother" star Neil Patrick Harris is reportedly in talks to do a guest spot.

"If I can make it work, it will be something that shoots at the end," Murphy told Entertainment Weekly. "He's very interested in the show and obviously Neil is a magician and likes all that magic stuff. ...  We're trying to make it work. I'm optimistic."

So what else does Murphy have planned for "American horror Story: Freak Show"?

"You will find out very early on. ... Why is [Twisty the clown] collecting children in the school bus?" Murphy said. "Well let it suffice to say that Dandy becomes Twisty's apprentice. ... I think Dot has eyes for Jimmy."

For those already looking toward Season 5 of "American Horror Story," Murphy says keep your eyes peeled during the first two episodes of Season 4.

"I figured out Season 5 very early on and I know that the fans love that," he said. "So there are clues that are dropped."
