Mullally, who received strong notices for her performance as the hot box dancer with a commitment-phobic fiance, told Playbill.com she would like to return to the role for an extended run — and that there is a possibility of her doing so.

"There's definitely talk of that, actually, that particular thing. But nothing's been nailed down," Mullally said.

Mullally was "tickled pink" to play Adelaide. "On the second day of rehearsal we had a table read and a sing through. I was just coming out of my shoes. I just couldn’t believe it," she said. "That was probably the first time I've ever gotten to show all of those things that I can do in a musical, in the same musical, on the same night, within the same two hour period of time. I've just never really gotten a chance to do a part, do a character that showed everything off in that way."

Mullally has long been a fan of musical theatre and described her childhood of performing for her mother, saying, "I would shut myself in my bedroom and sing along to records, and I would make up dances in front of the mirror and I would perfect them and have my mom come in and watch. I just have been trying, in my own little private quiet way... to hone my skills, not because I wanted to hone them, but because I loved doing it. "

Mullally's stage credits include Grease, How to Succeed in Business Without Really Trying and Young Frankenstein. The Emmy Award winner starred on the sitcom "Will & Grace."

She and Offerman frequently work together, both on stage and screen, and she considered the possibilities of a musical collaboration, mentioning Hello, Dolly! as an option.
