Celebrities switch places with the production crew in the new comedy-drama “The Producers,” as four top-tier stars ― Kim Soo-hyun, Cha Tae-hyun, Gong Hyo-jin and IU ― portray the hectic lives of broadcast television producer-directors.

Dubbed “the most anticipated show of 2015” by industry insiders, the new KBS drama will take us behind the scenes, revealing all the craze of overnight editing and endless meetings that go into producing variety shows, and promises light-hearted fun and laughter on the way.

The drama marks actor Kim Soo-hyun’s return to television after a one-year hiatus since the mega-hit drama “My Love from the Star.” In complete contrast to his role as charismatic alien Do Min-joon, this time, Kim will play a principled, book-smart rookie producer named Baek Seung-chan, who is painfully inarticulate, clumsy and not at all street-smart.

“Everybody was a rookie at some point in their lives,” said Kim in a press conference in Seoul on Monday. “So my goal is to let people relate to my character and remember that time.”

“He’s entirely clueless,” said Kim on his endearingly awkward role. “But he tries so earnestly not to be clueless, but that ends up irritating his superiors even more.”

In the show, Baek is constantly berated by Tak Ye-jin, the temperamental producer of popular music program “Music Bank.” Played by actress Gong Hyo-jin, Tak gives rookie employees a hard time with her straightforwardness, but is ultimately “human,” said Gong, and does her fair share of comical blundering.

“It’s the most aggravated, neurotic role I’ve ever taken on,” said the actress famed for sparking romantic chemistry in dramas like “Pasta” and “It’s Okay, That’s Love.”

“In the first episode, there are almost no scenes of (Ye-jin) smiling. She’s dissatisfied with everything, always telling people what to do ... but she’s imperfect and human, and writer Park Ji-eun makes her so charming.”

Alongside Gong’s character will be the hot-headed but soft-hearted variety show producer Ra Joon-mo, played by actor Cha Tae-hyun, who is well-loved for comic roles in box-office hits such as “My Sassy Girl” (2001).

It was easy for the seasoned actor to imagine himself on the other side of the scene.

“I’ve done so many things during the course of my career in the entertainment industry ― I’ve been a singer, an emcee, I’ve done radio and variety shows. I realized I’ve absorbed so much from all these experiences without even thinking about it,” said Cha.

Completing the star-studded cast will be singer-actress IU, who will play the haughty pop diva Cindy ― nicknamed “ice princess” for her complete emotional command and icy demeanor.

The singer said she observed and took tips from fellow singers to prepare for the role, but was also surprised at how similar the character was to her real-life self.

“Everyone has that irritated, touchy side to them,” she said, explaining that she was able to relate to the character’s biting attitude. “But Cindy is not all mean. The more I study her, the more I learn that she’s an innocent soul.” IU added that she is writing a song based on the character.

The drama has numerous references to real producer-directors like Na Young-seok and celebrity cameo appearances, including singer-producer and chief of JYP Entertainment Park Jin-young.

Helmed by comedy and variety show producer Seo Soo-min and penned by “My Love from the Stars” writer Park Ji-eun, “The Producers” will air Fridays and Saturdays at 9:15 p.m. starting May 15 and continue for 12 episodes, with each episode lasting 70 minutes.
