Will and Grace star Sean Hayes will be joining the cast of NBC's Smash as a comic TV star making his Broadway debut

It will be a Will & Grace reunion on NBC's primetime Broadway soap Smash this coming season when Sean Hayes (who played Will & Grace's flamboyant scene-stealer Jack McFarland on the successful sitcom) joins the much-buzzed-about television show featuring Debra Messing (Grace herself) for a multi-episode arc.

Hayes, who recently impressed Broadway in the revival of Promises, Promises as office drone Chuck Baxter, will play a character not unlike himself, a comic television star who is making his Broadway debut. Though unlike Hayes, who wisely chose a musical comedy to show off his Broadway chops, his Smash counterpart will be starring in a musical version of the seductive drama Les Liaisons Dangereuses. It has been reported that Sean Hayes' character, named Terrence Falls, will cause difficulty's for Smash's talented-but-overshadowed Broadway trouper Ivy (Megan Hilty). But it's not yet known how much screen time he will share with his old TV castmate Debra Messing, who plays Broadway show scribe Julia.
