Die Reise der Pinguine
The usage of computer-generated imagery became more widespread in films during the 2000s. Documentary and mockumentary films, such as "March of the Penguins" and "Super Size Me", were popular in the 2000s. 2004's "Fahrenheit 9/11" by Michael Moore is the highest-grossing documentary of all time. Online films became popular, and conversion to digital cinema started.
