Corrected entry: After the meteor shower, the two boys walk outside. Through the left window we can see the whole living room with the walls and furniture intact, even though the whole room was previously destroyed.
Corrected entry: In the scene where the game ejects Walter for cheating, the astronaut shoots into space and grabs onto Walter and brings him back into the house. Later when its revealed that the astronaut is really the older version of Walter they touch and the astronaut is "absorbed" back into Walter. Shouldn't that have happened when they first touched?
Correction: There is no "rule" in the movie that says when they touch the older one will disappear. He disappears later because he's done what he came to do.
Corrected entry: After the meteor shower, the brothers make a big deal of discovering that the shower only affected the living room. However, considering that everything else from the game affected the whole house, there's no particular reason from the logic of the movie alone that the shower only hit that one room. Keep in mind that after the shower when the boys look outside, the whole house is shown flying through the meteor-filled ring of a planet, making the 'living room only' shower even more surprising. Wherever the writers were going with this idea, it's left unexplained.
Correction: Unexplained yes, a plot hole, no. As soon as the first player goes we are in the world of the game, not the real world. Just because an event in the game is not fully explained that doesn't make it a mistake.
Corrected entry: Many non-scientific effects happen outside the house, most of them acceptable due to nature of film. However 'passing too close to the star' would not cause parts of the house to fall inwards as the house is in free-fall (in reality at that distance the characters would be roasted). Other examples: sofa burning in space, Zorgon ships turning without use of steering rockets although they use rockets to power the ships. Oh and where did the astronaut get his space suit from? Finally with regards to meteor shower. Big hole appears in roof from last one but there should be many small holes in the roof and upstairs floor from the little ones - but there aren't.
Correction: It's not the real world, it's the game world, so the game is in control of physics and reality and could easily have given the astronaut his suit because he couldn't play anymore, made the sofa burn, let the characters breathe, etc.
Corrected entry: A short while after Walter is chased around the house by the robot, Danny spins and gets a card. They begin to enter the sun's gravity field. The sun would have destroyed the house the minute they entered the gravity field.
Correction: The planet Earth is within the Sun's gravity field, yet somehow we all escape destruction every day.
Yeah, but the Earth is 91 million miles away from the Sun. In the movie it looks like the house is MUCH closer to it.
When the boys opened the front door when they first realised they're in space, they could breathe just fine. I think the game has powers to alter physics, such as allowing them to breathe in space. So I think the game altered how strong the gravity field was so there was some danger without it being instant death.
Corrected entry: In the scene where Danny goes into his dad's office, he says that he's ready to play "Smash Bros". The only problem is Smash Bros. is a Gamecube game and Danny is holding Playstation controllers. Later, when Walter and Danny are watching TV, a Playstation 2 is there, but a Gamecube is nowhere to be seen.
Correction: Super Smash Bros is also a game for the N64 console. I believe that Danny was holding a paddle for the N64. It's possible that they had one, but it wasn't visible.
You could make the same argument for the Gamecube. Looks like the directors screwed up on this one.
Correction: The living room was in the BACK of the house, directly behind the entry way. What you're seeing through that window is their father's office, which was not affected by the meteor shower.
