From a musical first on Horror Story to a post-Glee comedy with a deadly twist, Ryan Murphy's list of small screen hits is about to get even longer.
ET sat with the busiest producer in television to get exclusive new details on Lady Gaga's American Horror Story debut, the shocking Scream Queens twist no one knows about, and why John Travolta is bringing the "wow" factor to American Crime Story.
Fans were shocked last month when Gaga released the news that she would be checking into American Horror Story: Hotel as the new series lead, but Murphy revealed there's a specific reason the news was not leaked beforehand.
"It was just something that she did very, very privately. It was sort of a creative investigation," Murphy said of the music superstar's decision to star in the next chapter of the FX drama. "My favorite thing in the world would be when I would, of the blue, get a call from her and they'd say, 'Hold for Gaga'."
Although this is technically not Gaga's acting debut -- she hit the big screen in 2013's Machete Kills and 2014's Sin City: A Dame to Kill For -- this will be her first leading role in a critically acclaimed series.
But Murphy is not worried about Gaga stepping into the AHS spotlight now that Jessica Lange is officially done. "Well, I haven't seen her [acting] yet. But she studied acting and I think in many ways that's what she wanted to do first," the showrunner explained. "I think she's been looking for some outlet to really dig in there and create a character. I guarantee the role will shock people. What's she's playing."
Like every year, the character details of the new season are being kept tightly under wraps, but the news of which actors will be checking into Hotel are coming fast and furiously. At PaleyFest on Sunday, fans were thrilled to discover that both Matt Bomer (White Collar) and Cheyenne Jackson (30 Rock) will be joining the anthology cast.
Most recently, Murphy himself broke the news via Twitter on Tuesday morning that Wes Bentley, who briefly guest starred in Freak Show, will now be a series regular on AHS: Hotel.
With Glee coming to a series close this Friday, Murphy is already looking ahead to his next Fox comedy, Scream Queens. Although the "one-hour comedy" won't premiere until this fall, fans are already buzzing with excitement after learning that stars Lea Michele, Emma Roberts, Ariana Grande, Nick Jonas and many more are slated to appear.
"It's anthological in nature, but there's a catch to it," Murphy said of Scream Queens' secret twist. "I can't reveal because it's different than American Horror Story, which resets completely every year. This doesn't do that."
However the showrunner did share a few plot details that have never been released. "It is about the world's meanest sorority, and a series of bad things begin to happen," he explained. "Jamie Lee Curtis, who I've long really wanted to work with and I kind of wrote this series for, to be honest… she steps in and with the girls tries to figure out who's doing this -- and it's actually tied to an incident that happened 20 years ago at the college."
Murphy stressed that Scream Queens is going to keep you on the edge of your seat. "Every week, It's really like a murder mystery. Who's going to get knocked off? And who's the killer? And not until the last episode do you find out who it is," Murphy teased. "And everybody has the motivation to be that killer."
Another upcoming project that everyone is talking about is the premiere of Murphy's true-crime drama American Crime Story with the first season exploring the iconic O.J. Simpson court case.
Like all of Murphy's series, American Crime Story boasts a sensational cast including Cuba Gooding Jr., David Schwimmer, Sarah Paulson and John Travolta.
"When I asked to meet John Travolta and he said yes without having read any script it was amazing," Murphy recalled. "It made me re-remember when I was ten years old and I went to see Grease every weekend for like two months. So I was like, wow."
