Disney has announced that Avengers: Age of Ultron grossed $84.46M in it's first official day of release, which includes Thursday preview screenings. This is the second biggest opening day ever, and the second best single day in box office history. The numbers fall in line with industry estimates of $85 million. This puts the movie just behind Harry Potter and the Deathly Hallows - Part 2, which brought in $91.07M during its opening day back in 2011, and right above Marvel's The Avengers, which earned $80.8M during its first day bow in 2012.

Of the $84.46M, $27.6M came from Avengers: Age of Ultron's Thursday Night previews, which kicked off at 7pm. This was almost $10 million better than Marvel's The Avengers, which took in $18.7M during its Thursday midnight previews. Yesterday saw some wild estimates about just how much the movie would eventually claim on its first Friday. The number kept growing as theaters continued to add showtimes to meet high audience demands. And a lot of late night showtimes were added.

At both the famous Hollywood Arclight and New York City Regal E-Walk, screening numbers jumped from 43 to 52, while other major theaters are showing the Marvel sequel between 32 and 35 times a day to accommodate the high volume of demand. The film is screening on a higher number of screens than its predecessor.

Right now, industry insiders predict Avengers: Age of Ultron will finish the weekend with $202.6M, and that's incorporating the loss it will take during the Mayweather-Pacquiao fight. The movie also has NBA playoffs and the Kentucky Derby to contend with as well. If it only reaches $202.6M, it will fall just short of Marvel's The Avengers' $207.4M to have the second highest opening weekend of all time.
