An inside look at some of the secrets behind 'The Masked Singer'

"The Masked Singer" has been captivating audiences week after week, with millions tuning in to see if they can guess what celebrities are singing behind their respective masks.

Executive producer Craig Plestis had a hunch the show would be a hit when he saw the original Korean show in a restaurant.

"Everyone was watching it, I turned around, I saw it, it was like flypaper for me," Plestis said. "It was different and I gravitate toward things that are fresh and not derivative. So, when I saw that, I thought, 'There's something here.'"

Plestis said the clue packages are key to solve who's behind the mask.

"If you watch clue packages and we re-watch it again, you can figure out who that person is behind the mask," Plestis said. "And I want to give that ability."

Already planning for a second season, the contestant wish list is high.

"I would kill to have Obama on the show," Plestis said. "I don't think it's ever going to happen but that's an unexpected name to have someone like that in the mask, comes off to go 'Oh my God.'"

With millions wanting to know the celebs behind the mask, Plestis's biggest challenge is keeping the secret.

"We have a whole other department that's just a security-geared department, and that was Season 1 when no one knew, on no one's radar and we still implemented all that," Plestis said. "Season 2 is going to be monumental about keeping the secret."
