Comedy film is a genre of film in which the main emphasis is on humor. Also, films in this style typically have a happy ending. One of the oldest genres in film, some of the very first silent movies were comedies. Comedy, unlike other film genres, puts much more focus on individual stars, with many former stand-up comics transitioning to the film industry due to their popularity. While many comedic films are lighthearted stories with no intent other than to amuse, others contain political or social commentary (such as Wag the Dog and Man of the Year).

Types

A comedy of manners film satirises the manners and affectations of a social class, often represented by stock characters. The plot of the comedy is often concerned with an illicit love affair or some other scandal. However, the plot is generally less important than its witty dialogue. This form of comedy has a long ancestry, dating back at least as far as Much Ado about Nothing by William Shakespeare.

In a "fish out of water"-style comedy, the main character (or characters) finds himself in an unusual environment, which drives most of the humor. Situations can be swapping gender roles, as in Tootsie (1982); an age changing role, as in Big (1988); a freedom-loving individual fitting into a structured environment, as in Police Academy (1984); a rural backwoodsman in the big city, as in Crocodile Dundee, and so forth.

A parody or spoof film is a comedy that satirizes other film genres or classic films. Such films employ sarcasm, stereotyping, mockery of scenes from other films, and the obviousness of meaning in a character's actions. Examples of this form include Blazing Saddles (1974), Airplane! (1980), and Young Frankenstein (1974).

The anarchic comedy film uses nonsensical, stream-of-consciousness humor which often lampoons some form of authority. Films of this nature stem from a theatrical history of anarchic comedy on the stage. Well-known films of this sub-genre include Duck Soup (1933), National Lampoon's Animal House (1978) and Monty Python and the Holy Grail (1975).

The black comedy film deals with normally taboo subjects, including, death, murder, suicide and war, in a satirical manner. Examples include Arsenic and Old Lace (1944), Monsieur Verdoux (1947), Kind Hearts and Coronets (1949), The Ladykillers (1955), Dr. Strangelove or: How I Learned to Stop Worrying and Love the Bomb (1964), The Loved One (1965), MASH (1970), Monty Python's The Meaning of Life (1983), The War of the Roses (1989), Heathers(1989), and Keeping Mum(2005).

Gross-out films are a relatively recent development, and rely heavily on vulgar, sexual or "toilet" humour. Examples include Porky's (1982), Dumb and Dumber (1994), There's Something About Mary (1998), and American Pie (1999).
