Karen Gillan has been cast in a leading role in the sequel to 90s family film Jumanji.

The Scottish actress, 28, was welcomed to the “Jumanji family” by co-stars Dwayne Johnson and Kevin Hart, who both posted a picture of her on Instagram.

Dwayne wrote: “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.”

He continued: “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 film is a follow up to the 1995 movie starring the late Robin Williams.

Plot details have not been announced but the first film involved a magical board game.

Dwayne said: “This isn’t a remake or reboot, but a continuation of the awesome Jumanji story we love.”

Comedian and actor Kevin also welcomed Karen, who is probably best known for being a former Doctor Who companion.
