WEEKEND BOX OFFICE
Weekend box office charts show gross receipts for a given weekend, which is Friday through Sunday unless otherwise noted. Studio estimates for the weekend are reported on Sunday mornings, generally between 9 a.m. and 10 a.m. Pacific Time and reflect estimated Friday and Saturday box office receipts plus a projection for Sunday.

Actual weekend box office receipts are reported Monday, generally after 1 p.m. Pacific Time, and reflect most movies currently playing in the marketplace. A final update to the chart may be made Monday night or later in the week to reflect grosses that are reported late.
