VIDEO: Nathan Lane, Matthew Broderick Talk IT'S ONLY A PLAY on 'Tonight' - Hilarity Ensues!

On last night's TONIGHT SHOW, Jimmy Fallon talked with Nathan Lane and Matthew Broderick about their new Broadway comedy, It's Only a Play. Later, the host mixed up the traditional interview format by having the actors rotate with him, giving them all a chance to impersonate each other, and the long-time friends try to remember when they first met.

Then, in a web exclusive, Broderick and Lane recount their favorite onstage mishaps from their years of working together. Check out clips from last night's appearance below!

Previews of IT'S ONLY A PLAY began Thursday, August 28, 2014. The production will play a limited 18-week engagement at Broadway's Gerald Schoenfeld Theatre (236 West 45th Street) with an opening night set for Thursday, October 9, 2014.

Academy Award winner F. Murray Abraham, Tony Award winner Matthew Broderick, Emmy and Tony Award winner Stockard Channing, international film sensation Rupert Grint, Tony Award winner Nathan Lane, Emmy Award winner Megan Mullally, and newcomer Micah Stock star in IT'S ONLY A PLAY. Three-time Tony Award winner Jack O'Brien directs.

In IT'S ONLY A PLAY, it's opening night of Peter Austin's (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 (Lane), his fledgling producer (Mullally), his erratic leading lady (Channing), his wunderkind director (Grint), an infamous drama critic (Abraham), and a fresh-off-the-bus coat check attendant (Stock) on his first night in Manhattan. It's alternately raucous, ridiculous and tender -- and proves that sometimes the biggest laughs happen offstage.

Earlier this year, "The Tonight Show" returned to its New York origins when "The Tonight Show Starring Jimmy Fallon" made its broadcast debut from Studio 6B in Rockefeller Center. Emmy Award- and Grammy Award-winning comedian Jimmy Fallon will bring a high-tempo energy to the storied NBC franchise with his welcoming interview style, love of audience participation, spot-on impersonations and innovative sketches.
