As I said earlier to somebody else (stronghold?), for pictures from trailer it is maybe not a good idea to try to "guess" the star-rating of the cars. Unless you have seen the movie, of course.
Mmm, OK, but I thought I had a good impression of the car chases etc., or is an impression not good enough?
Should I make all cars 'unknown vehicle role'?
I am not sure, I think it is better to not mark the role without having seen the while movie, but on the other hand in some cases the trailer may give enough info on some of the cars.
Well, what's important is that if someone completes the page or sees the movie, he does not hesitate to correct the ratings.
Good point ... for example by wathing the trailer of the War of the Worlds (the one with Tom Cruise), you'd be tempted to consider the Mustang which slides in the trailer as part of the movie ... yet it get just a few shots and that's it.
..since your instructions (long ago) Not to add stars for film trailers ...i've stuck with this idea ...and now think it is best ..Not to have stars ..until the movie is fully seen.! ..for example ...if I clicked on this page to see if this movie was already listed...I would see all of these cars (..with stars.!) ..and think that the Movie had already been seen and completed.! ...so Not a good idea to add stars.!
