I wanted to come to a better conclusion, so I spent a few minutes tabulating the average running time of the top 50 movies of 2008. While not perfect, I think this gives a much better indication of the now, as opposed to the wow. And that number is 110 minutes.
I’ve always found it strange that everyone I know outside of my film geek circle tends to complain about the length of longer films, especially since the highest grossing films of all time are long. Below is a chart showing the running times of the top 14 grossing lie action films of all time. As you can see, all of the movies run over two hours, with some even running longer than three. The average run time is 159 minutes, or 2 hours and 39 minutes.
