If you are looking for a unique way to teach following a calling from God to high school youth groups, I would suggest Daredevil (yes the Ben Affleck movie)...it has amazing imagery, yes it is Catholic Church imagery, but we're all part of the church universal and it is a great dialogue starter.
Also to teach youth to share their faith stories, use Star Trek V.
