The Avengers: Age of Ultron’s second trailer has been released with new footage of Ultron blasting the Avengers, and Hulk fighting Iron Man.

While we expected a new trailer to land on February 1, during the NFL Super Bowl, we hadn’t expected to see a second trailer from Marvel so soon. After the film’s first trailer was released on October 22, it quickly became Marvel’s most-watched trailer ever released.

Marvel announced at the beginning of the month that the sequel’s second trailer would premiere during tonight’s College Football Championship. Now fans can watch The Avengers: Age of Ultron’s second official teaser trailer below:

In Age of Ultron’s second trailer, we see the Avengers seemingly battling each other after Ultron says he’s going to tear them apart, “from the inside out.” The last shot is the Hulk and Iron Man battling in the Hulkbuster suit.

There have been rumors that Ultron takes over the Hulk at one point, which is what we’re actually seeing in the trailer, but we won’t know if Tony Stark is using his Hulkbuster suit to battle the real Hulk or an Ultron-controlled Hulk until the film hits theaters.

The Avengers: Age of Ultron’s first trailer was incredibly well received, with a much darker tone than expected, and it seems that the second trailer has followed a similar path. Director Joss Whedon has explained that the sequel will still have its comedic elements, similar to the first film, but we’re absolutely loving the footage that’s been released so far.

Expect to see an enormous amount of new promotion for Avengers: Age of Ultron during the next few months, as we approach the film’s worldwide release. The Avengers’ sequel may be the most anticipated sequel of all time, especially for Marvel fans, and the studio will be going all out with Age of Ultron promotion over the next few weeks.

The Avengers: Age of Ultron will be released in theaters on May 1, 2015, with its follow-up being Avengers: Infinity War, which has been split into two parts and will be directed by Anthony and Joe Russo.
