There was a free plugin available from Adobe when you registered Premiere Pro called “Movie Looks”.
It takes forever and a day to render, but it might help you. Also, search on “Film Look” on this and other forums. Make sure you include the archives.
You will find that you should have worried about the lighting and the way you shot the video. After the fact is a bit too late to do too much about it.
