The game has changed in the first trailer for Jumanji: Welcome to the Jungle.

Unveiled this morning by star Dwayne Johnson, the teaser trailer lays out the premise for the sequel to 1995 fantasy adventure, in which four teens are transported into the dangerous world of an old video game they discover while cleaning the basement of their high school. There they find themselves transformed into avatars decidedly unlike their real-world counterparts.

In the brand new adventure Jumanji: Welcome to the Jungle, the tables are turned as four teenagers in detention are sucked into the world of Jumanji.

When they discover an old video game console with a game they’ve never heard of, they are immediately thrust into the game’s jungle setting, into the bodies of their avatars, played by Dwayne Johnson, Jack Black, Kevin Hart, and Karen Gillan. What they discover is that you don’t just play Jumanji – Jumanji plays you. They’ll have to go on the most dangerous adventure of their lives, or they’ll be stuck in the game forever ...

Arriving Dec. 20, director Jake Kasdan's Jumanji: Welcome to the Jungle stars Dwayne Johnson as Dr. Smolder Bravestone, Kevin Hart as Moose Finbarr, Jack Black as Professor Shelly Oberon, Karen Gillan as Ruby Roadhouse, and Nick Jonas as Alex.
