You can use http://www.imcdb.org/search.php then put in the year range ( if movie is from 1998-2002 the corresponding Pathfinder range would be 1996-2002 as we go by 1st possible model year ) , make and model

Once you have the results you can also click on any Pathfinder and then click on the code between [ ] as some vehicles can change name depending of the country the movie was filmed in but they often keep the same platform code

If you can't find it, maybe the movie wasn't included here yet
