Rocky: The Musical, the stage adaptation of the much-loved boxing film, has thrown in the towel after a six-month run. The musical was lately making just half of its weekly $1,263,688 revenue potential on Broadway.

Rocky, which premiered to rapturous reviews in Hamburg, Germany, in 2012, moved to Broadway in 2014. The musical recieved mixed to poor reviews upon its premiere, though most critics enjoyed a scene when the boxing ring is lowered on to the first few rows in the finale. The Guardian's Alexis Soloski gave it three stars, describing the musical's climax as "brutal, visceral and shamefully exciting".

Preview performances began on 13 February and the show officially opened a month later. When it closes on 17 August, it will have played 28 previews and 188 performances at New York's Winter Garden theatre.

Directed by Tony-nominated Alex Timbers, the musical was also co-produced by the original film lead, Sylvester Stallone, who wrote the film's screenplay, and Ukrainian boxing brothers Wladimir and Vitali Klitschko (the later is the new mayor of Kiev).

The musical adaptation followed the plot of the 1976 Academy Award-winning film, focusing on a small-time boxer, Rocky Balboa, who gets a rare opportunity to fight the heavyweight champion Apollo Creed. The original Rocky film was a sleeper hit, bringing in $225m on a $1m budget.

News of the closure comes shortly after Holler If Ya Hear Me, the Broadway production inspired by the music of the late rapper Tupac Shakur, announced it would end after a six-week run.
