Kirk Cameron and Chelsea Noble, both of Growing Pains fame, are back, making their rounds on the talk show circuit, talking about kids, faith and Kirk's new movie.

Cameron was once an atheist but has since become a Christian and started a ministry called Camp Firefly in Georgia that gives families with terminally ill children a weeklong paid vacation away form hospitals and doctors.

The 37-year old actor is starring in a new movie that will help raise money for his ministry.  In "Fireproof", Cameron's character is a heroic firefighter that is having marriage troubles at home.  Kirk says he put on about 15 pounds of pure muscle for the movie and even did his own stunts.

The movie opens September 26th.
