While the film was being made, Jonah Bobo (Danny) lost four teeth, so the filmmakers made 'flippers' or fake teeth that he wore, since the movie takes place in only a day.
When the house passes too close to Tsouris-3 and enters its gravity field, objects in the house and attached to the house begin to fall toward Tsouris-3 and away from the house, but all objects, including the house itself, would be subject to the same gravitational force and would fall toward Tsouris-3 together, as demonstrated by Galileo at the Leaning Tower of Pisa.

What are the differences between the British BBFC PG version and the Uncut Version?
A
Due to the usage of an aerosol as a blowtorch two scenes of the British version were cut in order to get a PG rating from the BBFC. In both cases shorter alternate material is used. A detailed comparison between both versions with pictures can be found here.
Q
Is this a sequel to Jumanji?
A
Both Jumanji and Zathura are based on novels by Chris Van Allsburg; in the book version of Zathura, the Zathura board game is found inside Jumanji, but an astronaut living inside Zathura claims to have created Jumanji.Zathura director Jon Favreau discouraged the notion that the film is a sequel to the earlier film Jumanji, having not particularly liked that film. Both he and Chris Van Allsburg stated that Zathura is very different from Jumanji. No characters from Jumanji appear in Zathura.However, reviewers disagreed, saying the films were very similar, one dismissing Zathura as "Jumanji in space without Robin Williams."
