Marvel's The Avengers had the highest domestic weekend opening at the box office in cinematic history with $207.4 million. So, of course all eyes are on Avengers: Age of Ultron, with many eager to see if it can beat it's predecessor and score a new box office record. As of now, Avengers 2 is tracking just a little better than the original did this same time back in 2012. The new film opens May 1, and has all of the main heroes from the original adventure returning, including Captain America, Thor, Iron Man, Hulk, Hawkeye, Black Widow and Nick Fury. We even get a few new costumed crime fighters with Quicksilver, Scarlet Witch and Vision joining the team.

Avengers: Age of Ultron will partake in advanced Thursday night previews on April 30, starting at 7pm. Advanced ticket sales for these shows began early last month, with the movie said to be 'significantly' outselling the first. A Fandango spokesperson revealed:

"Theaters around the country are sold out and managers are right now adding showtimes to meet the fan demand."

As of now, Avengers: Age of Ultron is tracking at the same rate as Iron Man 3. But that movie couldn't quite top Marvel's The Avengers weekend take, pulling in only $174.1 million during its debut, and grossing $409 million domestically through its run. It pulled in $1 billion worldwide. Does this mean Avengers: Age of Ultron won't be able to beat Marvel's The Avengers' opening weekend?

While the demos for Avengers: Age of Ultron are skewed towards a male audience, the female audience is in line with where a normal Marvel title usually is. The audience beyond the initial core, referred to as the 'unaided awareness' audience, don't quite have the film in their sights just yet, but that could easily change over the course of the next two weeks as Marvel ramps up its promotional efforts.

It's quite possible Avengers: Age of Ultron will score the highest grossing opening weekend in history. After its initial debut, Marvel's The Avengers went onto end its domestic run with $623.4 million, becoming the third highest grossing film in North America, resting just behind James Cameron's 2009 sci-fi adventure Avatar, which earned $760.5 million, and his 1997 classic Titanic, which earned $658.7 million. We'll be sure to update you with all the box office numbers as they come in throughout the May 1 weekend.
