Exclusive: NBC Sets Smash Reunion as Megan Hilty Joins Sean Hayes' New Fall Comedy

Megan Hilty Sean Saves the WorldAnd now for some rather Smash-ing news: Megan Hilty has landed a series regular role opposite her former Smash co-star Sean Hayes in his new NBC comedy Sean Saves the World, TVLine has learned exclusively.

Hilty will play Liz, the BFF and co-worker of Hayes’ character — the role originally portrayed by Lindsay Sloane, who left the project shortly after it was greenlit by NBC.

The multi-cam sitcom, which will air Thursdays at 9/8c, finds Hayes attempting to both parent the teenage daughter who just moved in and appease a temperamental new boss. (Watch the trailer.) The cast also includes Linda Lavin (Alice), Echo Kellum (Ben and Kate), Thomas Lennon (Reno 911!), Samantha Isler and Vik Sahay (Chuck).

On Smash, Hayes played a powerful but neurotic Hollywood star whose broad comic performance threatened (and eventually doomed) a Broadway musical version of Dangerous Liaisons. Hilty’s Ivy Lynn proved to be the sole cast member who could give Hayes’ flighty stae the completely unfiltered feedback he needed — leading to a bond that was occasionally sweet and very frequently zany.
