Frankly, if the look of the battle room is the worst thing about the movie vs. the book, I’d be delighted. 
I’m more worried about making the kids into teens.
Actually if memory serves:
just in case people haven’t read the book. They sent off the invasion fleet as soon as it was ready, something like 25 years previously right after the end of the first Bug War. By the time Ender is in Command School at the age of like 10 Mazer Rackham is about 60 or so - they sent him off somewhere in a ship and brought him back to take advantage of the whole Einstein speed of light changing how time flows on the ship thing. Sorry for not digging out the damned book to get all the references but it is in the barn and mrAru isn’t home from work to go dig it out.
The battle room in the book is described as having soft grey walls or something like that - very neutral so you can’t tel; anything by looking around. It is also not the huge center globe with a thin habitat wrapped around it, it is described as a series of rooms so multiple pairs of armies can practice or hold combat at the same time - they rotate somehow to allow different rooms to share sets of doors.
I only three stills from the movie, am I missing something, you guys seem to be talking from much more detailed photos then I am seeing.
Edit; 2 stills and a movie poster.
Did you actually READ the ARTICLE linked in THE OP?
[QUOTE=THE LINK in the OP!!!1]
Hood said he then proposed, “What if we could see through? What if we could see out of the space, and we’re moving around the Earth and turning at the same time?” He said he felt that would create “a really strange, disorienting experience,” that would better capture the notion in the book that in space there really is no up or down.

Earth isn’t going to be a fixed point.
Not that that’s going to make me go and see this, though - homophobe Card isn’t getting any of my money to funnel to his Conservative hate-buddies. Which is a pity, I usually like to support my countrymen in their international artistic efforts (although I’d already been burned by Wolverine)
In the poster, Ender who is obviously older than 6 or 8 years old is standing in the door to the battle room. In the book the battle room is described as being one of several that can be rotated into place for the students [who are sorted into teams which then spend their days between ‘classes’ in single team practice or 2 teams in set combat. There is a leader board to keep track of individual fighter stats and team stats] where they wear combat uniforms that mimic battle armor that will stiffen when hit by the laser pistol rendering them ‘dead’ for that phase of practice or battle. In the battle school, you start when you are 6 years old and take classes in logistics, tactics, mathematics, history and so forth. You arrive and are sorted into a team with the rest of the kids on your shuttle and assigned a team name and colors. Clothing is more or less optional males mixed with females. There are uniforms with your team colors. In the poster you see Ender with the colors and insignia of his team Dragons. In the 2 other pictures you see adolescents in battle school when they are the age that are either wiped out and sent back to earth to be in the regular navy, or sorted into flight school to be more or less air crew on a combat ship, or into command school where you learn to command ships and fleets.
If you are a fan of the books, the poster and pictures are more or less showing that they are not keeping the age range for battle school, the sets are incorrect - the racks [beds] are sticking out into the room like a hospital ward instead of being along the wall and showing the curveture of the space station. In the book Ender enters the dorm assigned to his flight [newbie combat group] and takes the first bottom rack next to the door, where there are lockers along the back row that are fingerprint locked, and the further back racks are not able to be seen because of the curve of the floor which is the external bulkhead of the section - the station being spun to give the sense of gravity.
Ender is supposed to be 8, right? I remember at a book signing back in 1994 or so OSC said that they were working on a movie and he wouldn’t let them make Ender older than 12. I guess he gave in there.
On a side note, I looked at the Wikipedia article for the book and was astonished to see a listing of TWENTY books and stories in the Ender series. Apparently Card is writing another new prequel series.
I would just caution against reading too much into the movie poster. They are often stylized compositions of various different aspects of the movie. The age thing is obvious from the stills, but the battle room I would reserve judgment.
Well I’m excited.
I did actually read the article, I just entirely disagree with their supposition.
In comparison to the small-ass room that they’re supposed to be in, having the solar system outside your tactical area (regardless of the spinning and revolution involved) remains a large, stable of itself, and potentially useful reference point if you know its there. These kids are all supposed to be staggering genuises, right? They’re going to be able to figure angles of rotation and momentum and work out where things will be when.
I’m sure it would be disorienting at first, but to me, the point of battle room wasn’t that it was disorienting, it was to select for people who were naturally good at nearly-instantly creating and implementing tactics in a changing situation with no outside materials (or visuals) to use to assist them. I remain convinced that having solar bodies hanging around would impede that particular goal, and that bugs me.
I liked that a good portion of Ender’s Game was that they were trying in every way they could to locate and groom the best military/tactical minds of the bunch.
Course I’m a grouch anyway, and probably won’t see it, so it really doesn’t much matter what I think anymore. There will be enough people that changes don’t bother to watch it, and even more who have never even heard of the book, and they won’t even realize there were changes made. Que sera sera.
There was a book?
lol took me a second to catch the username/posts combo here 
It’s not “supposition”, it’s the director’s own words - saying it was a deliberate choice to reinforce disorientation.
I’m sorry, I was unclear about the “supposition.” I know it was a deliberate choice on the part of the director/film design crew. I’ll use really short sentences this time: I think it is a STUPID CHOICE. I think that focusing on “disorientation” is MISSING THE POINT.
Obviously, the director doesn’t agree with my interpretation or he wouldn’t have done it that way. Obviously, other people (including the author, if he had creative input/veto power, which he might not have had) don’t share my interpretation, or my thought that it’s an important distinction. That’s fine. It doesn’t change my opinion.
I don’t know how else to try and get this idea across, so I’m now finished with this particular tangent.
In other news, has anyone else read the graphic novelizations and graphic novel prequels (about the actual invasion)? They’re actually pretty good. I’m enjoying them, and they’re fairly popular at my library.
Some people think that making the students older than the book had them is an unacceptable change. But this is going to be a tough movie to make, and even though it’s “make believe” some of it would be harrowing on actors that are very young.
Has anyone here ever seen the silent film “Broken Blossoms” starring Lillian Gish? It’s the sad story of a twelve year old girl who is beaten and derdidedby her drunken father, a washed out boxer. By the end of the film he has killed her. The director was the great D.W. Griffith. When Liilian asked him why he had her, a twenty-five year old woman playing a girl half her age she said he replied “What I’m going to put you through I wouldn’t want to do to an actual child.”
So maybe a decision was made to make them older. Or possibly,(and actually more likely) the younger the actor the harder to film, as there are increased regulations regarding working hours and safety.
Cool, more people will be exposed to Card’s cryptofascist amorality. Is Summit owned by Mormons, or do they just enjoy pushing their agenda?
