Paramount Pictures / Summit Entertainment
Pretty straight-forward here, but not as lopsided as it may seem. Kristen Stewart's lifetime gross, in 13 movies that earned enough to be counted by Box Office Mojo, is $731,936,579 (2 movies not counted) with "The Twilight Saga: New Moon" as the largest at $293,274,586.
Dakota Fanning's lifetime gross, in 15 movies counted, is $1,103,499,592 (3 movies not counted), with her biggest being "War of the Worlds" at $234,280,354.
Winner: Fanning. Although it seems that Fanning made so many more movies, she is only a couple ahead of Stewart.
