LOL I tried to watch that movie, but it ws so dumb that I wasn't really paying attention. I agree though that that is a huge oversight, especially in a post-apocaliptic world! I have a good one too; in the movie No Country for Old Men, the villian is driving down a quiet suburban road near the end of the movie, with a view out the driver window. One can clearly see a 2006 or 07 Subaru Forester in one of the driveways...the movie is set in the seventies...

I don't expect anyone to have a copy of this movie to check, I just thought I would mention it because it involved cars (and a semi).

There is a major mistake in Resident Evil: Extinction that I was wondering if anyone else caught. After the scene where the zombies attack the motorcade of people in Las Vegas, the lead scientist of the Umbrella corporation gets away in a helicopter. Alice surveys the lab from afar trying to figure out a way to steal the helicopter. Then the scene after that is the survivors of the attack recuperating near their vehicles in Vegas. There is one shot with a semi and two or three cars driving on a highway in the far distance. It's so obvious to see because they are the only things moving in the shot. Seriously, how could the director and everyone making the movie miss several cars and a semi driving on a highway? This happens approximately 20 minutes before the movie ends. This is one of the most ridiculous goofs I've seen in awhile, especially in a film that care about details, and making the atmosphere right.
