Making A "game Trailer"

[fomstudios]

Hey all,

I want to make a movie that looks like a game trailer, for personal use. Something that looks like a combination between the openings of Burnout 3/4, NFS: Most Wanted, and Battlefield 2. I want to have a few cars street racing through the city, with cops trailing, helicopters overhead, etc. This is just for fun, and I don't expect to finish it quickly (I don't mind if it takes a few months), but I don't know where to start.

I'm wondering how to animate the cars once I've made the models. Is there a way to use gravity to hold the wheels to the road? And how do you light the scene like there is a sun overhead, street lamps, etc?

Thanks!
