All time box office take

I would also like to see this down to actual tickets sold not dollars because prices increased far higher than the rate of inflation - which would put Avatar even further down the list. Also, I would like to see tickets sold relative to population. A large segment of the population for examples was not allowed into movie theaters during the time of Gone with the Wind. But there also wasn't the competition involved. Furthermore - many countries globally have opened up and allow western films to open whereas in the 1980's this was not the case.

So I think there are many many factors involved with selecting the most popular or seen movies. E.T. was in many theaters for over a year. Star Wars was in theaters for 44 weeks which likely means many people thought so highly of them they went back several times.

I saw Schindler's List in theaters 9 times for example and Pulp Fiction probably 3 or 4.
