A musical version of Rocky is set to debut in Germany in November 2012, Sylvester Stallone announced Monday in Cologne.
Stallone is teaming up with heavyweight champions Vitali and Wladimir Klitschko, who will co-produce the musical and train the actors in boxing.
Rocky: The Musical will debut next year in Hamburg. Casting has yet to take place.
The feature film Rocky won three Academy Awards in 1976, including Best Picture, and spawned five sequels that altogether grossed more than $1.25 billion worldwide. Stallone has long fancied the idea of bringing his most beloved film character to the stage.
"At the end of the day, Rocky is a love story and he could never have reached the final bell without Adrian,” Stallone said at Monday's announcement. “To see this story coming to life on a musical stage makes me proud. And it would make Rocky proud."
Budgeted at $15 million, Rocky: The Musical will have its world debut in German before Stallone brings an English-language version on tour around the world.
