Michael Sylvester Gardenzio Stallone, commonly known as Sylvester Stallone, and nicknamed Sly Stallone is known for his machismo and Hollywood action roles. Two of the notable characters he has portrayed are boxer Rocky Balboa and soldier John Rambo. The Rocky and Rambo franchises, along with several other films, strengthened his reputation as an actor and his box office earnings.

Stallone's film Rocky was inducted into the National Film Registry as well as having its film props placed in the Smithsonian Museum. Stallone's use of the front entrance to the Philadelphia Museum of Art in the Rocky series led the area to be nicknamed the Rocky Steps. Philadelphia has a statue of his Rocky character placed permanently near the museum, on the right side before the steps. It was announced on December 7, 2010 that Stallone was voted into boxing's Hall of Fame.
