It seems like most of the major characters from last year’s surprise Marvel hit “Guardians of the Galaxy” will be making a return to the big screen. Peter Quill (Chris Pratt), Gamora (Zoe Saldana), Drax (Dave Bautista), Rocket (Bradley Cooper) and Groot (Vin Diesel) are going back into space, but recent rumors suggest a new female Guardian maybe joining the group. Add that to the mystery of Peter Quill’s mysterious father, and there’s quite a few questions still left unanswered by the time “Guardians of the Galaxy 2” appears in theaters in a few years.

In a recent Twitter Q & A, director James Gunn hinted at which character he was eyeing to join “Guardians.”

Ah, let the speculating begin! There’s evidence to suggest it might be licensed character ROM Spaceknight, who appeared in the 2013 comic book version of Age of Ultron, the basis for the upcoming “Avengers” sequel. ROM’s parent company, Hasbro, had licensed the right rights to make new toys, but Marvel Studios hasn’t confirmed whether they’ve licensed the character for any upcoming movies (surprise).

But like many other Marvel announcements, we’ll be happy with occasional hints for the next few years.

If the first “Guardians” was a major risk with a relatively obscure property, its success (over $774 million internationally) gives Gunn license to veer away even further from the comic book storyline. It could very well be that Gunn opts to introduce a character of his own or from a different series altogether. He did confirm on the “Alison Rosen Is Your Next Best Friend” podcast that the upcoming sequel will be an original story he had been working on since the production of the original “Guardians.” He also hinted at the possibility of several new characters in the next installation.

For now, the secret remains safely in the hands of the current Collector, director James Gunn.

“Guardians of the Galaxy 2” will land in theaters nationwide May 5, 2017.
