Our gross figures are cumulative (i.e. they reflect the total amount of money grossed by a movie up to a certain date in the specified territory).
Some movie may also include partial weekend grosses that display the amount of money collected during that particular weekend. Weekend grosses are not cumulative: each weekend gross amount therefore doesn't include the money collected in the previous weekend.
A date of "final" next to a box office gross indicates the total amount of money collected during the film's whole release period.
