She's travelled through time and space in the TARDIS - but Doctor Who star Karen Gillan's most dangerous journey yet is into… a board game?!

Dwayne Johnson revealed today (August 30) that Gillan is joining himself and Kevin Hart in the Jumanji sequel because she possesses a very particular set of skills.

Dwayne revealed on Instagram: "Between myself, @kevinhart4real Jack Black and @NickJonas we've searched far and wide to find the one person to complete our #JUMANJI family. This isn't just any role, but in many ways the most important role of the movie. We had to find a girl. But not just any girl.

"A girl who has 'Chutzpah'. Guts, nerve and talent to stand her ground and hold her own against Nick's cool rockstar ways, Jack's relentless energy and genius, Kevin's masterful timing and skills and the big, brown, bald tattooed guy who just simply stands there and oooooozes smoldering, captivating, sizzling, can't take your eyes off this brilliant manly man.. never mind I got drunk on the ol' DJ kool aid again.

"Ladies and gentlemen, I'm proud to announce a girl who's playing the most important role in our movie - the talented, beautiful and down for a Scottish fight at any time, Ms @KarenGillanOfficial. And yes, this is the girl who is so bad ass she shaved her freaking head for Guardians of the Galaxy."

The original Jumanji starred the late great Robin Williams as a man who's spent 20 years trapped by snarling beasts in a magical board game.

Despite earlier reports, Dwayne Johnson has confirmed that his follow-up will actually be a direct Jumanji sequel rather than a reboot.

"For the record we are NOT making a reboot, but rather a continuation of the awesome JUMANJI story," The Rock wrote on Instagram.

Jumanji starts shooting in Hawaii next month and will crash into cinemas on July 28, 2017.
