The 2nd week is always a good indicator of how much people really like the movie.
Word of mouth gets out, so everyone who missed it the 1st week goes the 2nd week and the people who really loved the movie watch it again.
After scoring the second-best four-day opening of all time with $242 million and the best Monday ever at the domestic box office, Disney/Marvel’s Black Panther continued to knock over box office records, earning an estimated $21.07M on Tuesday. That’s the best pre-summer Tuesday take ever, beating Beauty and the Beast‘s haul for the day last year (March 21, 2017, $17.8M), and the best Tuesday ever for an Marvel Cinematic Universe title beating The Avengers ($17.6M).
Black Panther‘s Tuesday was down 48%, giving it a running five-day take of $263.2M, still the second best ever behind Force Awakens’ five-day run of $325.4M. The Star Wars movie crossed the three-century threshold in five days, the absolute record; it took Avengers nine days to get to that level. Black Panther should hit $300M by Friday (eight days), if not before. Black Panther is estimated to ease 55%-57% in Weekend 2 for $104M-$109M.
Among second-weekend champs, Force Awakens owns the crown with $149.2M (-40%), but in the MCU it’s The Avengers with $103M (-50%). In total, Black Panther will rank either second or third behind Force Awakens. Jurassic World has the second-best sophomore session with $106.5M
In the end, this will likely be a BILLION movie worldwide.
