On Thursday's Watch What Happens Live, host Andy Cohen asks the 58-year-old actress what it would take for herself and her co-stars, Debra Messing, Eric McCormack and Sean Hayes, to agree to star in a revamp of the beloved series.
"I would assume they'd have to back up three dump trucks worth of money to get you guys to do it," Cohen tells Mullally. "Am I correct in that, or has enough time passed that you're like, 'It was so fun, we'd do it for one dump truck of money?'"
"Well, you know, like, three [dump trucks worth of money] is good," Mullally quips.
As for whether there have been "official talks" about bringing back Will & Grace, the actress coyly responds, "Well, there is some interest and people have been talking, there's some rumors. From what I can tell, a lot of people really want the show to come back so we'll see what happens."
She jokingly adds that if the series did come back that "it'd probably be a 12-part miniseries with each installment being four hours long."
In September, Mullally and her co-stars reprised their sitcom roles for a 10-minute video that encouraged Americans to vote in the 2016 presidential election. "It was kinda like we had just been away for the weekend. The best part was that it was all the same people," she says of the reunion. "Not just the cast, Jim Burrows the director, the costume designer, the lighting designer, the set designer, the writers, everybody the same, the camera operators..."
Mullally also candidly talks about the "worst behavior" she witnessed when guest stars would come on Will & Grace. "People were pretty nice but I don't know about bad behavior," she explains. "But some people got so nervous that there was fainting, throwing up and, you know, just general bodily shut down."
