The Fast and Furious star
took to Instagram on Thursday to debut a tentative look at his character, the "smoldering" Dr. Bravestone -- who appears to be an Indiana Jones-esque explorer.
Johnson poked fun at the artistic rendering in the caption, writing, "not sure where my pecs went," but the star seemed really excited about the upcoming project.
"This is gonna be fun," Johnson wrote. "Can't wait to 'play the game that plays you.'"
In director Jake Kasdan's continuation of the original Jumanji, released in 1995, Johnson is set to take on the infamous board game alongside his Central Intelligence co-star Kevin Hart, Jack Black, Doctor Who's Karen Gillan and Nick Jonas.
"The love and respect I have for this man is boundless," Johnson wrote in a touching Instagram post back in May. "You have my word, we will honor his name and the character of Alan Parrish will stand alone and be forever immortalized in the world of Jumanji in an earnest and cool way. I have an idea of what to do and I think his family will be proud."
sequel is yet another in a long line of massive blockbusters starring the former professional wrestler,
who recently landed at the top of Forbes' list of the world's highest-paid actor.
