One of the strange aliens from the first Guardians of the Galaxy movie probably won't be back for volume two.
Benicio del Toro told ComingSoon that he "doesn't think so," as far as a Collector return for the sequel. "They would have told me, I hope... I do hope to play that character again at some point."
His character first showed up in the post-credits sequence for Thor: The Dark World. The sequence was shot and directed by James Gunn, who wrote and is directing the new film. One of the reasons the Collector might not be returning for this particular adventure is that del Toro himself will be off on a different Disney space adventure. The actor has a role, heavily rumored to be a primary villain, in Star Wars: Episode VIII. That film, from Lucasfilm, is scheduled to hit theaters exactly three weeks after GOTG v2, from sister company Marvel Studios, in May 2017.
