Fireproof — Easter Eggs & Hidden Details

Alex Kendrick, who directed and co-wrote the film, makes a brief on-screen appearance at the very end of the movie as the pastor who officiates Caleb and Catherine's vow renewal ceremony.

Throughout the film, Caleb operates under the assumption that his father used The Love Dare to save his parents' marriage years ago. In a late-stage twist, it is revealed that it was actually Caleb's mother who used the dare on his father, subverting expectations and proving that the fight for a marriage goes both ways.
