Alrighty. I noticed when watching Red Planet the other day, that there is advertising on the suits worn by the ground crew that travels to the Martian Surface...
In that shot, you can see Toshiba, GM, Nokia, and Hughes.
In Mission to Mars, you can see advertising on the ground vehicle...
Now... I get the idea of advertising on sports figures/vehicles. The public are watching them, so you slap some logos on them to drive home brand recognition. However... the only people who would be seeing these logos in the universes detailed by these two movies, are the members of the crew on the ground on Mars. There are no public spectators to see this advertising.
If we look at it from the point of view of it being a movie, rather than being immersed in the story, then the advertising is for the people watching the movie... and ONLY for the people watching the movie. Wouldn't that be blatantly breaking the fourth wall?
