VIDEO: Megan Mullally Talks IT'S ONLY A PLAY & More on TONIGHT

Megan Mullally stopped by NBC's TONIGHT SHOW WITH JIMMY FALLON to talk about her Broadway show, It's Only a Play and recalls seeing her first naked man on stage. Check out the appearance below!

The star-studded Broadway production of the backstage comedy It's Only A Play, by 4-time Tony® Award winner Terrence McNally, officially opened at Broadway's Gerald Schoenfeld Theatre (236 West 45th Street) on Thursday, October 9, 2014.

The show stars Academy Award® winner F. Murray Abraham, Tony® Award winner Matthew Broderick, Emmy® and Tony® Award winner Stockard Channing, international film sensationRupert Grint, Tony® Award winner Nathan Lane, Emmy® Award winner Megan Mullally, and newcomer Micah Stock star in It's Only a Play. 3-time Tony® Award winner Jack O'Brien directs.

In It's Only A Play, it's opening night of Peter Austin's (Matthew Broderick) new play as he anxiously awaits to see if his show is a hit. With his career on the line, he shares his big First Night with his best friend, a television star (Nathan Lane), his fledgling producer (Megan Mullally), his erratic leading lady (Stockard Channing), his wunderkind director (Rupert Grint), an infamous drama critic (F. Murray Abraham), and a fresh-off-the-bus coat check attendant (Micah Stock) on his first night in Manhattan. It's alternately raucous, ridiculous and tender - and proves that sometimes the biggest laughs happen offstage.
