Context paragraphs:
Brain Donors: Brain Donors (1992) is an American comedy movie released by Paramount Pictures, loosely based on the Marx Brothers comedies "A Night at the Opera" and "A Day at the Races" (the two films the Marx Brothers did after leaving Paramount).

American comedy films: American comedy films are comedy films produced in the United States.  The genre is one of the oldest in American cinema; some of the very first silent movies were comedies, as slapstick comedy often relies on visual depictions, without requiring sound.  With the advent of sound in the late 1920s and 1930s, comedic dialogue rose in prominence in the work of film comedians such as W. C. Fields and the Marx Brothers.  By the 1950s, the television industry had become serious competition for the movie industry.  The 1960s saw an increasing number of broad, star-packed comedies.  In the 1970s, black comedies were popular.  Leading figures in the 1970s were Woody Allen and Mel Brooks.  One of the major developments of the 1990s was the re-emergence of the romantic comedy film.  Another development was the increasing use of "gross-out humour".

Zeppo Marx: Herbert Manfred Marx (February 25, 1901 – November 30, 1979), better known by his stage name, Zeppo Marx, was an American actor, comedian, theatrical agent, and engineer.  He was the youngest of the five Marx Brothers.  He appeared in the first five Marx Brothers feature films, from 1929 to 1933, but then left the act to start his second career as an engineer and theatrical agent.  Zeppo Marx was a multi-millionaire due to his engineering efforts.

Horse Feathers: Horse Feathers (1932) is a Pre-Code Marx Brothers film comedy.  It stars the four Marx Brothers (Groucho, Chico, Harpo and Zeppo) and Thelma Todd.  It was written by Bert Kalmar, Harry Ruby, S. J. Perelman, and Will B. Johnstone.  Kalmar and Ruby also wrote some of the original music for the film.  Several of the film's gags were taken from the Marx Brothers' stage comedy from the 1900s, "Fun in Hi Skule".  The term "horse feathers" was a colloquial American expression for "nonsense" in the 1920s and 1930s but is now archaic.

Nancy Marchand: Nancy Marchand (June 19, 1928 – June 18, 2000) was an American actress.  She began her career in theatre in 1951.  She was perhaps most famous for her television portrayals of Margaret Pynchon on "Lou Grant" and Livia Soprano on "The Sopranos".

Chico Marx: Leonard Marx (March 22, 1887 – October 11, 1961), known professionally as Chico Marx, was an American comedian, musician, bandleader, actor and film star.  He was a member of the Marx Brothers (Groucho Marx, Harpo Marx, and Zeppo Marx).  His persona in the act was that of a charming, dim-witted albeit crafty con artist, seemingly of rural Italian origin, who wore shabby clothes and sported a curly-haired wig and Tyrolean hat.  In virtually every film that includes the main trio of the Marx Brothers, Chico is seen working with Harpo Marx, usually as partners in crime.  Leonard was the oldest of the Marx Brothers to live past early childhood (first-born Manfred Marx had died in infancy).  In addition to his work as a performer, he played an important role in the management and development of the act in its early years.

Mary Dees: Mary Ella Dees (June 3, 1911 – August 4, 2004) was an American stage and screen actress who once served as a primary stand-in double for late-1930s actress Jean Harlow.  Dees had parts in "The Last Gangster" (1937), "The Women" (1939), as well as a number of Three Stooges shorts, which included "Hoi Polloi" (1935), and numerous Marx Brothers comedies.
