Data on movies is very useful from a statistical learning perspective. Instructors of statistics & machine learning programs use movie data instead of dryer & more esoteric data sets to explain key concepts. Since movies are universally understood, teaching statistics becomes easier since the domain is not that hard to understand.

Movielens Data by GroupLens

GroupLens Research has collected and made available rating data sets from the MovieLens web site (

http://movielens.org

). The data sets were collected over various periods of time, depending on the size of the set. Before using these data sets, please review their README files for the usage licenses and other details.

UC Irvine Machine Learning Lab’s Movie Data Set

This data set contains a list of over 10000 films including many older, odd, and cult films. There is information on actors, casts, directors, producers, studios, etc. The data is stored in relational form across several files. The central file (MAIN) is a list of movies, each with a unique identifier. These identifiers may change in successive versions. The actors (CAST) for those movies are listed with their roles in a distinct file. More information about individual actors (ACTORS) is in a third file. All directors in MAIN are listed in a fourth file (PEOPLE), with a number of important producers, writers, and cinematographers. A fifth file (REMAKES) links movies that were copied to a substantial extent from each other. The sixth file (STUDIOS) provides some information about studios shown in MAIN.

Hadley Wickham’s Normalized IMDB Movie Data

IMDB makes their raw data available. Unfortunately, the data is divided into many text files and the format of each file differs slightly. To create one data file containing all the desired information Wickham wrote a script in the ruby to extract the relevant information and store in a database. This data was then exported into csv for easy import into many programs. The following text files were downloaded and used:



business.list. : Total budget



Genres.list. Genres that a movie belongs to (eg. comedy and action)



movies.list. Master list of all movie titles with year of production.



mpaa-ratings-reasons.list. MPAA ratings.



ratings.list. IMDB fan ratings.



running-times.list. Movie length in minutes.



AM Stat Movie Data Set

The Movie dataset contains weekend and daily per theater box office receipt data as well as total U.S. gross receipts for a set of 49 movies. Dates are provided for all time series values. The diverse list of movies was selected, not at random, but to spark student interest and to provide a range of box office values. The values provide a rich dataset to use for applications such as simple graphical analysis, a variety of time series and causal forecasting models, curve-fitting, and rate of change analysis. A series of assignment questions is included and the accompanying Instructor’s Manual provides representative solutions.
