The ninth season will run for 12 episodes, NBC has confirmed. "In the States, they’ve never brought a show back – the same exact show [with the] same cast, same director, same lighting designer,” says actress Megan Mullally. “The main priority is to have it be funny, and then I think it just goes from there.”
Megan also joked about what her character would be up to in 2017: "“People would ask me, ‘What do you think Karen will be doing now?’ I think she’ll be married to Donald Trump!'
This isn't the first time Will & Grace has technically made a return: they did a one-off short election presidential election scene last year. For those who missed it, you can check it out here:

There's been a long-ish funny clip and and a short official trailer put up on social media websites this week to announce the return of the popular comedy show's new 12 episodes. You can check them out here...
