I'm not sure how well known any of the actors are but the lead male is a Mexican superstar and is considered their "BRAD PITT!" Either way, they did a great job. If I remember correctly this movie was a smaller budget film that had not been given a wide run of theatres at first. A lot of churches helped push the film and gave it extra advertising, allowing it to run in more cities.
I'm glad I got a chance to see it. It does run into a slow spot in the middle but overall, it is worth the view.
Probably not a movie for young children as they may not "get it." I would give it four popcorns because of it's positive theme.
