They are an unassuming multi-media power couple. Author, columnist and humorist W. Bruce Cameron's novel "A Dog's Purpose" spent a year on the New York Times bestseller list. Another of his 13 books, "8 Simple Rules for Dating my Teenage Daughter" became an ABC TV series. Cameron met his actress, director, screenwriter, comedian wife Cathryn Michon on a book tour. The author of the "Grrl Genius" book series, Michon has written for numerous TV shows, ranging from "China Beach" and "Designing Women" to "Southpark."

Now the husband and wife have joined forces to bring his bestselling "novel for humans", "A Dog's Purpose" to the big screen.

FOX's Jane Metzler talks with Cameron and Michon about the film, which stars Dennis Quaid and Josh Gad, how Michon inspired her husband to write "A Dog's Purpose" and its sequel, "A Dog's Journey," and their involvement in a charity that could revolutionize cancer detection. It, too, involves dogs:
