It was confirmed earlier this year that the popular sitcom was coming back for a new series, a decade after it was last on screens.
Will and Grace ended in 2007 after eight successful seasons.
The show followed the story of best friends Will Truman and Grace Adler, as well as their pals Karen Walker and Jack McFarland.
The cast first reunited for a 10 minute US election special in November last year.

It was later confirmed that US channel NBC had ordered a full new series.
Though the Will and Grace revival was originally set for ten episodes, it was later extended to twelve.
Now, after months of waiting, the first trailer for upcoming new series has been released.
In the hilarious clip, Eric McCormack, who plays Will, is seen trying to convince Debra Messing, who plays Grace, to take part in the reboot.
As the actress admits she’s reluctant to portray Grace again, Eric takes her back to the famous Will and Grace set.
In the apartment that Will and Grace shared, the stars discover Karen actress Megan Mullally on the sofa.

When questioned about what she’s doing, Megan states that she was having a nap.
As Eric tells her they’ve been “gone for ten years,” she hilariously replies: “Well I must have needed the sleep.”
Soon enough, actor Sean Hayes bursts through the apartment door in character as the theatre-loving Jack.
The famous foursome then perform an elaborate musical routine, insisting the new episodes will be “like they never said goodbye.”
After the sing along, an exhausted Eric states: “Well that was gay.”
At the time the new series of Will and Grace was announced, NBC Entertainment Chairman Robert Greenblatt said: “We’re thrilled that one of the smartest, funniest and most defining comedies in NBC history is coming back.

“This groundbreaking series for everything from gay rights to social and political commentary – all disguised as a high-speed train of witty pop culture – is coming back where it belongs.”
Confirming the news herself when questioned by a fan, Debra wrote on Twitter: “It’s TRUE!”
Jennifer Salke, president of NBC Entertainment, later added: “We started talking with Mutchnick and Kohan about producing new episodes right after they shot the secret reunion show back in September.
“The fact that all four of the original stars were excited about getting back into production is a testament to the joyful experience they had doing nearly 200 episodes for eight seasons.”

She added: “Few things cut through the clutter these days, especially in comedy, and Will and Grace is one of the best.”
Will and Grace will return for twelve new episodes in Autumn this year.
