Photos: Go Backstage with the Cast of MR. SATURDAY NIGHT on on Opening Night!

The new comedy musical, Mr. Saturday Night officially opened on Broadway last night at the Nederlander Theatre and BroadwayWorld was there and we're taking you behind the scenes to check out all of the backstage action!

MR. SATURDAY NIGHT is the story of Buddy Young Jr., an outrageous and outspoken comedian who found fame, if not fortune, in the early days of television. Now, some 40 years after his TV career flamed out, Buddy seeks one more shot at the spotlight, and while he's at it, one last shot at fixing the family he fractured along the way.

Billy Crystal returns to the role of Buddy Young Jr. that he portrayed in the original 1992 Columbia Pictures film of the same name, which also marked his directorial debut. Mr. Saturday Night also features Tony Award winner Randy Graff (City of Angels, Les Misérables) as Elaine Young; David Paymer (City Slickers, Quiz Show, State & Main), who is recreating his Oscar-nominated performance as Buddy's brother Stan Yankleman; Shoshana Bean (Wicked, Waitress) as Susan Young; and Chasten Harmon (The Good Fight, Elementary, Broadway's Hair) as agent Annie Wells. The Broadway company will also include Jordan Gelber (Sunday in the Park with George), Brian Gonzales (Aladdin), and Mylinda Hull (Dirty Rotten Scoundrels, Sweet Charity), Stephen DeRosa (Gary: A Sequel) Henry Gainza (On Your Feet), Tari Kelly (Groundhog Day) and Tatiana Wechsler (Broadway debut).

The book for the stage musical is written by Billy Crystal, Lowell Ganz and Babaloo Mandel. The score for Mr. Saturday Night features music by three-time Tony Award winner Jason Robert Brown (Parade, The Bridges of Madison County) and lyrics by Tony Award nominee Amanda Green (Hands on a Hardbody). Tony Award winner John Rando (Urinetown, On The Town) will direct. The production will feature choreography by Ellenore Scott (upcoming revival of Funny Girl).
