Eclipse has now broken it's 2nd record, but falls short of 1st day New Moon numbers.
From Box Office Mojo:
Playing on approximately 8,000 screens at an opening-record 4,416 locations, Eclipse still had a phenomenal
debut, setting two other records. The vampire romance sequel boasted the
largest Wednesday gross of all time, surpassing Transformers:
Revenge of the Fallen's $62 million. It also logged the
top-grossing summer day ever, surpassing The Dark
Knight's $67.2 million.
Overall, Eclipse posted the second highest-grossing single day of all time, behind only its predecessor.
The last time June 30 landed on Wednesday and Independence Day landed on Sunday was in 2004. That's when Spider-Man
2 established the record for that holiday. It made $40.4
million on its Wednesday opening, or the equivalent of around $52
million adjusted for ticket price inflation. By its sixth day, it had
pulled in $180.1 million, or more than $230 million adjusted.
Even after opening on more screens than New Moon, New Moon's 1st day was higher.
Eclipse's full day came in at an estimated $68.5 million, falling short of New Moon's $72.7 million record ($26.3 million of which from its midnight launch)
