And what can we expect from next week’s season finale?
Series executive producer Craig Plestis answers all of our burning questions, below.
Plus, EW is debuting an exclusive preview of the season 5 finale.
CRAIG PLESTIS:We haven’t had the idea for that long, to be honest.
That’s how it kind of manifested itself.
The idea for this character, too, was to plant Easter eggs all the way through.
And how did Donnie get involved?
So in regards to Donnie, I kept thinking about who would be the best person.
This was over the holidays, in fact, when this all happened.
Can we actually pull this off?
Our show is a double double secret show, so let’s do it all the way."
So, I called him up, and he said yes.
But it was great all the way through.
She had no idea.
He kept it completely secret.
It was just a triumph.
How did you guys manage to keep it a secret from her on set?
Although, really all the thank yous go to Donnie for not telling his wife.
That was the hard part right there.
The easy part was keeping the secret on the production side.
You mentioned there were Easter eggs from Donnie that no one caught.
Can you give an example?
There were Easter eggs with Donnie all the way through the show.
And he did it!
He just loved playing the game all the way through and got a thrill out of it.
So Jenny didn’t recognize his singing voice on stage or his real voice?
So it proved to be a great success.
We were just so happy that it was organic.
No one is expecting someone to come out and do a song and dance, either.
Was Cluedle-Doo’s performance always part of the plan?
I’m glad that this all worked out.
And he really did it for the fans as well.
He just had a ball doing it and keeping the secret and you saw that reaction.
Everything was so honest, it was so great.
Well, you know what, I think Cluedle-Doo was really a great success for the season.
Let’s wait and find out.
What can you tell me about next week’s finale?
Don’t miss it.
We have three powerhouses and it’s anybody’s game.
We have LeAnn Rimes coming back,our winner from last season.
It’s an action-packed episode.
We’ve got three incredible performances.
These are some of the biggest performances we’ve had all season.
There’s three incredible unmaskings, and of course, one grand winner from those three.
The Masked Singerseason 5 finale airs Wednesday at 8 p.m. ET/PT on Fox.
