"Someone figured out long ago that audiences can only sit for a movie for around two, maybe three hours, before they and their bladders begin to lose patience. So if a movie demands more than that, or even twice as long as that, it'd better be worth investing an entire afternoon to see, when you account for bathroom and snack breaks. Luckily, we've found several four-hour-plus behemoths that are worth every one of the 240 or more minutes you'll spend watching them. Many were originally TV miniseries. Some were released in parts before being reassembled into a single movie. Some are merely the longest versions of movies with multiple different cuts. Most are historical epics of one degree or another, examining major world events through the eyes of either famous figures or fictional characters who simply try to survive as the world shifts and changes, often violently, around them. Some others are fantasy masterpieces, superhero team-ups, or hauntingly shot documentaries." - looper.com
