More cast members were revealed by director James Gunn.

— -- "Guardians of the Galaxy" director James Gunn just announced a pretty big addition to the sequel of his surprise 2014 blockbuster.

"Official photography on Guardians of the Galaxy Vol. 2 has started, and I couldn't be more stoked," Gunn posted this morning on Facebook. "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."

Russell, 64, had been rumored to be in the movie.

Gunn went on to reveal more names who will star in the Marvel film.

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

The director promised more surprises in the coming months, which all comic fans hope is a possible Hulk cameo. The last we saw of the green monster, he was in "Avengers: Age of Ultron" and took off in a Quinjet, maybe to outer space?
