This is not a list of personal favorites. It is an average of ten different published "Funniest Movies" lists.
Comedy film is a genre of film in which the main emphasis is on humour. These films are designed to elicit laughter from the audience. Comedies are generally light-hearted dramas and are made to amuse and entertain the audiences. The comedy genre often humorously exaggerates situations, ways of speaking, or the action and characters.
Scientific research has proven which movie is the funniest of all time.
Airplane! generates an average of THREE laughs per minute!

Results are based on the averages of the following ten lists of the funniest movies of all time:
Sources were selected based on numbers of people contributing and variety of perspectives (the last three are British or European sources and none were lists posted online by individuals).
When possible, the top 30 movies on each list were used for this study and each film was given a score based on its rank (1 for first on the list, 30 for the bottom of the list.) If a film was not on the list at all, it was given a 45 score (1.5 times the bottom of the list). Two lists were less than 30 movies long, so anything not included on them was assigned 1.5 times the score of the lowest on the list.
Attached is the Excel spreadsheet with the raw data and the full list with scores.
This is the OFFICIAL LIST of the funniest movies ever made (as of 2013). See below for the research process that was used in making the list.
