Question: Cliffhanger starred which actor who played Rocky Balboa?
Context: Rocky Balboa: The Best of Rocky is a compilation album of music and short dialogue clips from all six "Rocky" films, named after the sixth installment, "Rocky Balboa".  It was released on December 26, 2006 by Capitol Records, the same day as the 30th anniversary re-release of the original "Rocky" soundtrack. Cliffhanger is a 1993 American action adventure film directed by Renny Harlin and starring Sylvester Stallone, John Lithgow, Michael Rooker and Janine Turner.  Based on a concept by climber John Long, the film follows Gabe (played by Stallone, who co-wrote the screenplay), a mountain climber who becomes embroiled in the failed heist of a U.S. Treasury plane flying through the Rocky Mountains.  The film earned $255 million worldwide. Rogues of Sherwood Forest is a 1950 Technicolor Columbia Pictures film directed by Gordon Douglas and featuring John Derek as Robin the Earl of Huntingdon, the son of Robin Hood, Diana Lynn as Lady Marianne, and Alan Hale, Sr. in his third movie as Little John over a 28-year span; he'd played the part opposite Douglas Fairbanks in 1922 and Errol Flynn in 1938, one of the longest periods over which any film actor played the same major role.  (Sylvester Stallone played Rocky Balboa over an even longer span, between 1976 and 2015.)  It was also Hale's final film.  The film was written by Ralph Gilbert Bettison and George Bruce. "Gonna Fly Now", also known as "Theme from "Rocky"", is the theme song from the movie "Rocky", composed by Bill Conti with lyrics by Carol Connors and Ayn Robbins, and performed by DeEtta West and Nelson Pigford.  Released in February 1977 with the movie "Rocky", the song became part of American popular culture after main character Rocky Balboa as part of his daily training regimen runs up the 72 stone steps leading to the entrance of the Philadelphia Museum of Art in Philadelphia and raises his arms in a victory pose, while the song plays.  The song was written in Philadelphia.  The song is also often played at sporting events, especially at sporting events in the city of Philadelphia or featuring sports teams from there. Michael Sylvester "Sly" Gardenzio Stallone ( ; ] ; born July 6, 1946) is an American actor and filmmaker.  He is well known for his Hollywood action roles, including boxer Rocky Balboa, the title character of the "Rocky" series' seven films from 1976 to 2015; soldier John Rambo from the four "Rambo" films, released between 1982 and 2008; and Barney Ross in the three "The Expendables" films from 2010 to 2014.

Rocky Balboa also known as Rocky VI is a 2006 American sports drama film written, directed by, and starring Sylvester Stallone.  The film, which features Stallone as underdog boxer Rocky Balboa, is the sixth film in the "Rocky" series that began with the Academy Award-winning "Rocky" thirty years earlier in 1976.  The film portrays an aging Balboa in retirement, a widower living in Philadelphia, and the owner and operator of a local Italian restaurant called "Adrian's," named after his late wife. Apollo Creed is a fictional character from the "Rocky" films, initially portrayed as the undisputed heavyweight champion of the world.  He was played by Carl Weathers.  He is a tough but agile African-American boxer.  The character was inspired by the real-life champion Muhammad Ali, having what one author remarked as the same "brash, vocal, [and] theatrical" personality.  Protagonist Rocky Balboa, Creed's rival in "Rocky" and "Rocky II", faces underdog odds (five-to-one in "Rocky II") and views Creed with respect, pointedly refusing the prodding of a reporter to "trash talk" against Creed by laconically remarking, "He's great."
