The 25-year-old star appears alongside Dwayne 'The Rock' Johnson, Kevin Hart, Jack Black and Karen Gillan in the sequel to the 1995 Robin Williams classic, 'Jumanji: Welcome to the Jungle', and said he "fell in love with all these characters" when reading the script.

Speaking exclusively to BANG Showbiz at the UK premiere of the new film at Vue Cinema in London's Leicester Square on Thursday (07.12.17), Jonas said: "I was obviously a huge fan of the original.

"Robin Williams' performance is brilliant. The film as a whole is one of my favourites so to be able to be part of something like this that has a legacy like that, is something special.

"But when I read the script, I fell in love with all these characters. And the use of the body swap in this way was really original and I knew they would nail it. And this cast is just dynamite."

Unlike the original, the new film follows four high school teenagers who discover an old video game console and are transported into the game's jungle setting, becoming the adult avatars they chose.

The four must work together to survive in the jungle and beat the game in order to return to the real world or they will be stuck forever.

'Jumanji: Welcome to the Jungle' features a stellar cast of comedians and Jonas said it was "sometimes funnier" once the cameras stopped rolling.

He shared: "It was just as funny off-screen, maybe sometimes funnier. We all had a great time together.

"You know, on top of getting all the work done and being professional, we did have a lot of fun and did our best to make the environment for everybody on set really special."
