Question: Three Ages is a film starring an American actor who earned what nickname?
Context: Paul Albert "Mousie" Garner (July 31, 1909 – August 8, 2004) was an American actor.  Garner earned his nickname by assuming the role of a shy, simpering jokester.  Garner was one of the last actors still doing shtick from vaudeville, and has been referred to as "The Grand Old Man Of Vaudeville." American actor and director Morgan Freeman has had a prolific career on film, television and on the stage.  His film debut was as an uncredited character in the Sidney Lumet–directed drama "The Pawnbroker" in 1964.  Freeman also made his stage debut in the same year by appearing in the musical "Hello, Dolly! " He followed this with further stage appearances in "The Niggerlovers" (1967), "The Dozens" (1969), "Exhibition" (1969), and the musical "Purlie" (1970–71).  He played various characters on the children's television series "The Electric Company" (1971–77).  Freeman subsequently appeared in the films "Teachers" in 1984, and "Marie" in 1985 before making his breakthrough with 1987's "Street Smart".  His role earned him a nomination for the Academy Award for Best Supporting Actor.  Two years later he appeared in war film "Glory" (1989), and starred as Hoke Coleburn in the comedy-drama "Driving Miss Daisy" (1989).  Freeman won the Golden Globe Award for Best Actor – Motion Picture Musical or Comedy for his performance in the latter and also earned a nomination for the Academy Award for Best Actor. Eddie Barth (September 29, 1931 – May 28, 2010) was an American actor and voiceover artist.  Barth earned the nickname, Mr. Gravel, for his raspy vocals in his voiceover work. Lon Chaney (April 1, 1883 – August 26, 1930), born Leonidas Frank Chaney, was an American actor during the age of silent films.  He is regarded as one of the most versatile and powerful actors of early cinema, renowned for his characterizations of tortured, often grotesque and afflicted characters, and his groundbreaking artistry with makeup.  Chaney is known for his starring roles in such silent horror films as "The Hunchback of Notre Dame" (1923) and "The Phantom of the Opera" (1925).  His ability to transform himself using makeup techniques he developed earned him the nickname "The Man of a Thousand Faces." Three Ages is a 1923 black-and-white American feature-length silent comedy film starring comedian Buster Keaton and Wallace Beery.  The first feature Keaton wrote, directed, produced, and starred in (unlike "The Saphead" (1920), in which he only acted), Keaton structured the film like three inter-cut short films.  The structure also worked as a satire of D. W. Griffith's 1916 film "Intolerance".  The film was shot in this manner as a kind of insurance for the studio.  While Keaton was a proven success in the short film medium, he had yet to prove himself as a feature-length star.  Had the project flopped, the film would have been broken into three short films, each covering one of the 'Ages.' Joseph Frank "Buster" Keaton (October 4, 1895 – February 1, 1966) was an American actor, comedian, film director, producer, screenwriter, and stunt performer.  He was best known for his silent films, in which his trademark was physical comedy with a consistently stoic, deadpan expression, earning him the nickname "The Great Stone Face."  Critic Roger Ebert wrote of Keaton's "extraordinary period from 1920 to 1929, [when] he worked without interruption on a series of films that make him, arguably, the greatest actor–director in the history of the movies".  His career declined afterward with a dispiriting loss of his artistic independence when he was hired by Metro-Goldwyn-Mayer and he descended into alcoholism, ruining his family life.  He recovered in the 1940s, remarried, and revived his career to a degree as an honored comic performer for the rest of his life, earning an Academy Honorary Award in 1959. Kevin Tighe (b. Jon Kevin Fishburn; August 13, 1944) is an American actor who has worked in television, film, and theatre since the late 1960s.  He attended University of Southern California where he earned a Master of Fine Arts in acting.  Tighe earned a role in "The Graduate" starring Dustin Hoffman and then served in the U.S. Army.  Following his military service, he returned to acting, working under contract for Paramount Pictures.  In 1971 he signed a contract with Universal Studios and got the part of Fireman Roy DeSoto on the NBC series "Emergency! " (1972–77).  He has made many guest appearances in TV shows such as "Ellery Queen", "Cos", and "The Hardy Boys/Nancy Drew Mysteries".  Tighe's film credits include "Road House", "What's Eating Gilbert Grape", and "Jade".  Tighe won a Genie Award for best supporting actor in 1994 for "I Love a Man in Uniform".  In the 2000s he played Anthony Cooper, the father of John Locke, on the ABC series "Lost". Lee White (August 28, 1888 – December 16, 1949), better known as Lee "Lasses" White, was an American actor of the stage, screen and radio.  He became famous doing minstrel shows during the early part of the 1900s, during which time he earned his nickname of "Lasses", which was short for Molasses.  After spending some time on radio, White entered the film industry in the late 1930s.  During his eleven-year career, he appeared in over 70 films. Rod Steiger was an American actor who had an extensive career in film, television, and stage.  He made his stage debut in 1946 with Civic Repertory Theatre's production of the melodrama "Curse you, Jack Dalton!" .  Four years later, he played onstage in a production of "An Enemy of the People" at the Music Box Theatre.  A small role in Fred Zinnemann's "Teresa" (1951) marked his film debut.  In 1953, he played the title role in the teleplay "Marty" (two years before the film starring Ernest Borgnine) to critical praise.  His breakthrough role came with the crime drama "On the Waterfront" (1954), which earned him an Academy Award for Best Supporting Actor nomination, and subsequent appearance in Fred Zinnemann's musical "Oklahoma! ". Justin Henry Worthington (born May 25, 1971) is an American actor, known for playing the object of the titular custody battle in the 1979 film "Kramer vs. Kramer", a debut role that earned him a nomination for the Academy Award for Best Supporting Actor, when he was eight years old.  As of 2016, he is the youngest actor to be nominated in any category, and the only actor ever nominated in the same decade as his or her birth.  The performance later earned him a spot (No. 80) on VH1's list of 100 Greatest Kid Stars.  Most of his film and television credits came as a child or teenager, although he has continued acting as an adult.
