Maybe you haven't heard of this movie. It wasn't a Hollywood big-budget production. In fact, it was done almost entirely on volunteer work. Remember Kirk Cameron, from Growing Pains? He's the only "real" actor in the movie.
So you're probably not excited, huh? Let me tell you - this is hands-down the best relationship movie I've ever seen. I was amazed to see how accurately it portrays relationships - not just in the main character's marriage, but in the relationships of all the characters.
Rather than bore you with my account, just check out the website for Fireproof. If your marriage is anything less than perfect, I highly recommend seeing it.
