Two familiar faces from James Gunn’s “Guardians of the Galaxy” are not coming back for the sequel. Screenrant reports that director James Gunn revealed in a Q&A on Facebook that actor John C. Reilly and Benicio Del Toro will not return for “Guardians of the Galaxy Vol. 2”. Reilly played the character Corpsman Dey and Del Toro played The Collector. The sequel will explore Star Lord’s parentage.

“John C. Reilly is not back for Volume 2, unfortunately,” said director Gunn. Regarding Del Toro, he confirmed that the latter will not appear in the sequel as well because he “just didn’t fit into Volume 2.” Gunn hopes Del Toro will appear in some form in the Marvel expanded universe, the series of movies to come. “I’m very excited to see him in the MCU in the future, I hope.” Nothing is certain, though.

A quick search through the work schedules of the two actors reveals that they are both involved in some very high-profile projects. Reilly will appear in Jordan Vogt-Roberts’ “Kong: Skull Island,” while Del Toro is filming scenes for Rian Johnson’s “Star Wars Episode VIII.” So, it is understandable that their commitments prevented them from being part of Guardians Volume 2 even if they were considered to be a part of it. If there’s a third Guardians movie, then these actors might return.

The Independent is also reporting that Josh Brolin, who played Thanos in an uncredited post-credits scene in “Guardians of the Galaxy,” will also not appear in the sequel. Thanos is expected to be a key villain in the MCU Phase 3.

As for the new members, actors Kurt Russell, Elizabeth Debicki, Pom Klementieff, and Chris Sullivan are joining returning members Chris Pratt, Zoe Saldana, Dave Bautista, Michael Rooker, Karen Gillan, Vin Diesel, Bradley Cooper, Sean Gunn, and Glenn Close. The official statement by Gunn, as per The Independent, is as follows:

“Official photography on Guardians of the Galaxy Vol. 2 has started, and I couldn’t be more stoked.

My favorite movie as a small child was The Strongest Man in the World, so I’m glad to announce that, yes, Kurt Russell has joined our cast and, yes, he is more awesome a dude than I ever could have imagined.

The last few days around here with him and our other new cast members, Pom Klementieff, Elizabeth Debicki, and Chris Sullivan, have been some of the best of my life. I never thought anyone was missing from our island of misfit toys, but now that these folks are here there feels like there was.

Chris Pratt, Zoe Saldana, Dave Bautista, Michael Rooker, Karen Gillan, Vin Diesel, Bradley Cooper, Sean Gunn, and Glenn Close are all returning.

We’ll have more surprises for you in the coming months. But, for now, this will have to do.

I have to get back to set!

Have a great day, everybody.”

“Guardians of the Galaxy Vol. 2” opens in the United States on May 5, 2017.
