In August 2016, Dwayne Johnson confirmed that the film will not be a reboot or a remake, but a sequel to the original film and a tribute to Robin Williams.

In the aftermath of Jumanji (1995) actor Robin Williams's suicide, many people spoke out against this film. The crew assured that this film would provide a great tribute to Williams.

The film's African jungle setting was shot in Hawaii.

Tom Holland was cast as Seaplane McDonough but had to drop out of the film and was replaced with Nick Jonas.

It had been speculated that Karen Gillan's character was either Alan Parish's daughter or a grown up Judy Shepherd (Played in the 1995 film by Kirsten Dunst).

As of April 22, 2016, Dwayne Johnson (The Rock) confirmed via Twitter that he will star in this film and that shooting will start in Fall 2016.

Jumanji (1995) is one of Karen Gillan's favorite films.

The idea of the main characters getting sucked into the game itself rather than staying in the real world is similar to the Jumanji animated series, which itself was an altered retelling of the first Jumanji movie.

The 3rd adventure film set in the jungle to star Jack Black. Jack Black had starred in King Kong (2005) as the filmmaker Carl Denham, and Tropic Thunder (2008) playing an actor, Jeff Portnoy. In this film, he plays a virtual character.

Karen Gillan recorded a video for her official Instagram account on the set with her stunt doubles and stated that being an actress is hard.

Jack Black had starred opposite Catherine Tate in Gulliver's Travels (2010). Both Catherine Tate and Karen Gillan had starred in Doctor Who (2005) and both actresses are natural redheads.

It was speculated that the film would be about Dwayne Johnson, Karen Gillan, Kevin Hart and Jack Black's characters finding the board game and being sucked into the world of Jumanji and setting out to find a way of escaping back into the real world.

Jack Black and Jake Kasdan have worked together on Orange County (2002).

17 years before the movie's release, Dwayne Johnson had appeared in Star Trek: Voyager (2000) (TV Series) as The Champion. Karen Gillan is a fan of Star Trek: The Next Generation (1987) (TV Series).
