Robert "Rocky" Balboa is the title character of the "Rocky" series.
 The character was created by Sylvester Stallone, who also portrayed him in all seven "Rocky" films.
 He is depicted as an everyman who started out by going the distance and overcoming obstacles that had occurred in his life and career as a professional boxer.
 While he is loosely based on Chuck Wepner, a one-time boxer who fought Muhammad Ali and lost on a TKO in the 15th round, the inspiration for the name, iconography and fighting style came from boxing legend Rocky Marciano.
Rocky Marciano fought two celebrated boxing matches with Ezzard Charles.
 The first match took place on 17 June, 1954; and the second on 17 September, 1954.
 The first fight went the distance with Marciano winning on points through a unanimous decision.
 In the second bout Marciano knocked out Charles in the eighth round.
Sparring with Hemingway is a book written by Budd Schulberg consisting of a collection of Schulberg's articles on boxing spanning nearly half a century.
 The book includes descriptions of fights between Marciano and Archie Moore; Ali and Foreman; Leonard and Duran; and Hagler and Hearns.
 A review of the book in the "New York Times" praises Schulberg's technical expertise on the subject of boxing.
 A "Chicago Tribune" review of the book states: The pieces in the present volume range over the whole of Schulberg's career and include those drawn from his days as a reporter for the New York Post as well as assignments for Sports Illustrated and other publications.
 He chronicles the demise of Archie Moore, the implacable assaults of Rocky Marciano, the supernova-like appearance of Cassius Clay and his psych job on the theretofore-invincible Sonny Liston, the saga of Mike Tyson (predicting long before Tyson's conviction on rape charges that "the biggest fight of all may still be Tyson vs. Tyson") and the resurrection of George Foreman: "Win or lose, this 260 pounds of fighting preacher has proved what . . . F. Scott Fitzgerald denied when he wrote, `There are no second acts in American lives.' "
The Super Fight was a fictional boxing match between Rocky Marciano and Muhammad Ali shot in 1969.
 At the time, Ali and Marciano were the only undefeated heavyweight champions in history and fans often debated who would win had they met in their primes.
 Ali and Marciano were filmed acting out every possible scenario in a fight and the result was then determined using probability formulas entered into a computer.
 The final fight was only shown once in select cinemas around the world and released as a DVD over three decades later.
Rocky Marciano is a 1999 television film directed by Charles Winkler and presented by MGM.
 It tells the story of the rise to fame of legendary boxer Rocky Marciano.
In combat sports such as boxing, an orthodox stance is one in which the boxer places his left foot farther in front of the right foot, thus having his weaker side closer to the opponent.
 As it favors the stronger, dominant side—often the right side, see laterality—the orthodox stance is the most common stance in boxing.
 It is mostly used by right-handed boxers.
 Many boxing champions—such as Jack Johnson, Anthony Joshua, Marco Antonio Barrera, Rocky Marciano, Ingmar Johansson, Roberto Durán, Floyd Mayweather Jr., Muhammad Ali, Amir Khan, Peter Buckley, Johnny Tapia, Mike Tyson, Larry Holmes, Lennox Lewis, and Wladimir Klitschko —fought in an orthodox stance.
