2011 The Sequeliest Year In Hollywood History
27 sequels total. Nine second movies (up from eight in 2010), five third movies (down from seven), five fourth movies, five fifth movies, two seventh movies and one eighth movie. 9+5+5+5+2+1=27.
Wow, that's a lot of movies to be based on other movies. The worst part is that since this beats the previous record holder 2003 by 3 movies, we can't just blame Martin Lawrence for this.
