Two main differences were the color and the one in the movie was running people down or doing other things to people who wronged them somehow. Until I actually watched the movie, I always thought the car was blue like in this episode.

More about miscellaneous Super I stuff, this is where I could stand one of those sucking sound effects things that they use on The Simpsons for the baby because that's the name of the girl who has what looks like normal attraction to Alex.
Take care and God bless
