Photo Flash: ROCKY Preps for Broadway Bow: In Rehearsal with Andy Karl, Terence Archie & Margo Seibert

The new musical ROCKY begins previews February 11 at Broadway's historic Winter Garden Theatre ahead of an officialy bow on March 13. Below, check out just-released rehearsal photos with stars Andy Karl, Terence Archie and Margo Seibert!

ROCKY brings to life the iconic and inspiring story of struggling small time Philly boxer, Rocky Balboa, who gets a once-in-a-lifetime shot to go the distance against heavyweight champ Apollo Creed. Both an adrenaline-infused spectacle and a surprising story of blossoming romance between two lonely outsiders, ROCKY is a heart-stopping and viscerally theatrical new musical for everyone brave enough to follow their dream.

ROCKY features an original score by Stephen Flaherty and Lynn Ahrens, the celebrated Tony Award-winning and Academy Award-nominated songwriters behind Ragtime, Once on This Island, and Anastasia, and a book by multiple Tony Award-winner Thomas Meehan (The Producers, Hairspray, Annie) and Sylvester Stallone, who was nominated for an Academy Award for Best Original Screenplay for the 1976 Oscar-winning Best Picture, Rocky.

The production is directed by Alex Timbers, the Tony-nominated director behind the acclaimed musicals Here Lies Love and Bloody, Bloody Andrew Jackson, as well as Peter and the Starcatcher, which continues to run off-Broadway. The musical features choreography by Steven Hoggett, who received a Tony Award nomination for his work on Once and Kelly Devine, best known for the long-running Broadway hit Rock of Ages.

The ROCKY cast features Andy Karl (Rocky), Margo Seibert (Adrian), Terence Archie (Apollo Creed), Dakin Matthews (Mickey) Danny Mastrogiorgio (Paulie), Jennifer Mudge (Gloria) and ensemble members Adrian Aguilar, Eric Anderson, Michelle Aravena, James Brown III, Sam J.
