Following the news that Guardians of the Galaxy Vol. 2 star Karen Gillian has joined the cast of the upcoming Jumanji reboot/sequel, Dwayne “The Rock” Johnson has taken to Instagram to offer up a first look at some concept art of the movie’s lead hero along with some details.

Named Dr. Bravestone, the image doesn’t exactly do Johnson’s physique justice – something he jokingly acknowledges in the post below – but it definitely gives off something of an Indiana Jones vibe. It’s fair to say that’s not a role most of us have imagined him in, but the wrestler turned actor ¬†looks the part here. How his character factors into Jumanji remains to be seen as plot details are being kept under wraps, so this artwork is particularly intriguing.

It will be fun to see if the rest of the cast reveals similar concept art over the coming weeks and months. Either way, Johnson is a master when it comes to building buzz, so Jumanji may go from being a movie people are sceptical about to one they’re counting down the days to.
