Its natural to compare the upcoming FOX series “Running Wilde” to “Arrested Development,” but they’re actually nothing alike.

The sitcom stars Will Arnett and was created by Arnett, “Arrested Development” creator Mitch Hurwitz and writer Jim Vallely. The show revolves around Steven Wilde (Arnett), a spoiled playboy who has it all except the love of his childhood sweetheart Emmy Kadubic (Keri Russell), who’s as liberal, eco-friendly and humanitarian as they come. His complete opposite. The series also co-stars Peter Serafinowicz and David Cross.

“It’s different, there’s a burden association with ‘Arrested Development’ that’s a high class problem to have,” Hurwitz has said, adding, “We’re glad to be working and doing something that appeals to a wider audience …[and once we achieve that] more and more of our subversion will be able to come out.”

But, Hurwitz doesn’t want to change “Running Wilde” into “Arrested Development 2.0″.

“There’s real peril in trying to repeat yourself and trying to apply rules that apply to something else to a new project,” he said. “[FOX chief] Kevin Reilly has been unbelievably helpful in helping us ground this and helping me get out my comfort zone. Sometimes it’s easier to write those unlikable characters because they do funnier things.”

Those characters are exactly what drew Keri Russell to the project. At the TCAs she said, “I just wanted to be interested and it was interesting to me. I’d been reading a lot of film scripts that were more of the same. The type of movies I did want to make weren’t being made. This came my way and it was too good to pass up. It was fresh and exciting and I thought I’d try it.”

“Running Wilde” premieres on Sept. 21 on FOX.
