Earlier today, we showed you a new set video from Jumanji 2, which had Jack Black 'shutting down' production, with that report also including some casting news, with Rhys Darby and Morgan Turner coming aboard. Dwayne Johnson took to social media once again today to reval that Morgan Turner is one of four new characters that the actor calls "Jumanji Juniors," with Ser'Darius Blain, Madison Iseman and Alex Wolff playing the other Juniors. Here's what Dwayne Johnson had to say on Instagram about these Jumanji Juniors.

"Officially welcoming our #JumanjiJuniors to our film. Talented young actors @serdariusblain @madisoniseman @natandalex & @Mozefro. As you guys know, we're not making a remake or reboot, but rather a continuation of our 1995 classic we all love. Survive or die stakes with our brilliantly funny motley crew of Kevin Hart, Karen Gillan and Jack Black. And yes its true.. I am in fact playing a man named "Smolder Bravestone", 'cause well... he smolders. Good Lord. #Jumanji The adventure continues.. SUMMER 2017."

The Hollywood Reporter has even more story details about Jumanji 2, revealing that Alex Wolff, the brother of The Stand and Death Note star Nat Wolff, is playing a young boy named Spencer. His avatar in the Jumanji game is Dwayne Johnson's character, Dr. Smolder Bravestone. Ser'Darius Blain, Madison Iseman and Morgan Turner are playing the other "real-world kids," but we don't know which avatars will represent them.

Earlier this week, the first Jumanji 2 photo was released featuring Dwayne Johnson, Kevin Hart, Jack Black and Karen Gillan, which was heavily criticized since all of the male stars were fully dressed, while Karen Gillan's costume was quite skimpy. The actress took to Twitter, revealing there is a good reason she is wearing "child sized clothes," which many have theorized could mean that her character has been trapped in the game since she was a kid, and has simply grown out of those clothes. It seems this theory may be true, but we'll have to wait and see if Dwayne Johnson or Karen Gillan offer more details soon.

In the original movie, siblings Peter (Bradley Pierce) and Judy Shepherd (Kirsten Dunst) find Alan Parrish (Robin Williams), who has been stuck in the game's inner world for decades, with the kids given a chance to free him if they can beat the game. Dwayne Johnson has said numerous times that this movie will honor Robin Williams' character, although no specific details have been given.
