The following are non-definitive lists of the actors with the highest career-film grosses. There are box-office gross revenue lists, which are not adjusted for inflation, as well as lists for the number of box-office ticket sales. Because of the long-term effects of inflation on movie theater ticket prices, a list unadjusted for inflation gives far more weight to later actors. Therefore, the gross revenue lists are largely meaningless for comparing acting careers widely separated in time, as many actors from earlier eras will never appear on a modern unadjusted list, despite their films' achieving higher commercial success when adjusted for price increases.
