In the movies, stormtroopers are soldiers for the evil Galactic Empire.

In our reality, they can do good. Take Kevin Doyle, for example. He walked 645 miles down the California coast in memory of his late wife. His wife, Eileen, died of pancreatic cancer.

Doyle started walking from an area north of San Fransisco in early June. He arrived at San Diego's Comic-Con over a month later.

He walked to raise money for Eileen's Little Angels, an organization that gives money to kids who are going through chemotherapy.

He is going to walk home from San Diego as well. He told associates of that the walk to Comic-Con was for her. The walk back is for him to heal, finish his grieving process, and to let go.

Star Wars may have inspired more people than any movie in history, and the best may be yet to come. Check out the Comic-Con reel for the 2015 Star Wars film.
