As expected, 'Avengers: Age of Ultron' enjoyed an extremely successful opening Thursday night, however that is nothing compared to its entire opening weekend.

Thursday's box office pull of $27.6 million shatters its predecessor's record of $18.7 million in 2012. While there was a huge spike in the coming weekend, there were some perceived variables that may have deterred sales.

"Reuniting Robert Downey Jr., Chris Evans, Chris Hemsworth, Scarlett Johansson, Mark Ruffalo, Jeremy Renner, Samuel L. Jackson and Cobie Smulders, joined by new Avengers played by Elizabeth Olsen, Aaron Taylor-Johnson and Paul Bettany, all to fight James Spader's Ultron, it scored the second-biggest single day on Friday (including Thursday previews) with $84.5 million. With so much sports-related competition on Saturday including the Kentucky Derby, the big Mayweather-Pacquaio brawl and the seventh game in the Spurs/Clippers playoffs series, the movie took a significant tumble on Saturday to the point where Disney ended up lowering its weekend estimate to $187.7 million," writes Coming Soon.

While 'Ultron' didn't hit its weekend goal of around $210 and 220 million, it can still claim the second-biggest opening weekend in North America.

The movie also had some record breaking numbers in IMAX theaters.

"The movie is another significant hit for the IMAX Corporation following Furious 7 as they had their first ever $30 million weekend between the two movies with Age of Ultron accounting for $25.2 million on global IMAX screens and Furious 7 doing another $5 million in China and Japan (where Age of Ultron has yet to open). Domestic IMAX theaters accounted for $18 million of that amount on 364 screens with another $7.2 million on 221 IMAX screens in 50 territories. That weekend IMAX gross for Age of Ultron tops the previous global IMAX record (not including China) that was held by The Dark Knight Rises with $23.8 million," writes Coming Soon.
