Are new movies longer than they were 10, 20, 50 year ago?

If you like to watch movies and I mean a lot of movies, there is a chance that you noticed that movies are getting longer and longer nowadays. When was the last time you went to the cinema and watched blockbuster which was shorter than 120 minutes? More and more movies (thank you Marvel for encouraging this trend!) have also scenes after subtitles, so you wait patiently all the way till the end, even if your bladder is killing you for some time already.
