Long before "Guardians of the Galaxy" hit theaters back in 2014, it had found itself being labeled as Marvel Studios' first "box office bomb." This, of course, stemmed from the fact that, not only were the characters unknown to the general pubic, but the idea that they'd be able to properly market a film featuring a gun-toting raccoon and a walking, talking tree -- which is why it was a huge surprise when the film ended up over-performing in its opening weekend, going from a $65 million opening weekend estimate, to over $90 million in its opening weekend. Those aren't "Avengers" numbers, but they were proof enough that Marvel Studios had yet another hit franchise on its hand. With that said, we're now a few months out from the release of the highly-anticipated sequel, and box office experts are beginning to offer up their own expectations for the film, and it looks like "Guardians of the Galaxy Vol. 2" is set to be another box office success for Marvel Studios.

According to Box Office Pro, the sequel is set to open to a massive $160 million. That's well above 2014's "Guardians of the Galaxy," and in line with what we've come to expect from sequels in the Marvel Cinematic Universe. As the site notes, the forthcoming sequel has been topping social media in the past few months as Marvel has upped their marketing campaign, making it more interactive for fans through sites like Twitter and Facebook.

Of course, this far out from release, tracking estimates are just that -- estimates. It's hard to get a clear idea of how well a film will do until approximately three weeks out from release. However, previous Marvel films, more specifically the "Captain America" films, have shown that sequels within the Marvel Cinematic Universe tend to improve on their predecessors and "Guardians of the Galaxy Vol. 2" appears to be no different.
