List of highest-grossing second weekends for films

The following is a list of the highest-grossing second weekends for films. Usually by the second weekend in the U.S. and Canada, studios can have an idea of what the final gross may be now that factors such as word-of-mouth and increased competition are starting to show. Many films usually have big drops as they could be "frontloaded" as fans want to watch them on opening weekend to be first to see it, but some could stay relatively modest as word-of-mouth works in the films' favor. The following shows how much the film has dropped compared to its opening weekend. Like the highest-grossing openings, the list is dominated by recent films due to steadily increasing production and marketing budgets, and modern films opening on more screens. Another contributing factor is inflation not being taken into account.
