The movie about saving lives that has saved marriages has also saved some Christian bookstores. The makers of Fireproof, who also co-authored the best-selling tie-in book The Love Dare, told yesterday how they have heard from Christian retailers who attribute strong sales of the book-now with 3 million in print-and DVD to keeping them in business.

Brothers Alex and Stephen Kendrick spoke of the stories they had heard of how their efforts had impacted stores, when the pair visited the show yesterday to meet retailers. Among them was Lynette DeRose, manager of House of Peace in Evergreen Park, Ill., who said that the two titles had "done great" at the store. "There's not a lot of things we have had to re-order like that."

Stephen Kendrick said he and his brother had been thrilled with the way Fireproof and The Love Dare had not only impacted countless marriages, but also had helped Christian bookstores. "Our prayer from the beginning has been, Lord bless everyone who partners with us, who has a part in this journey," he said.

The pair is currently working on The Love Dare Day by Day Devotional, which is due to be published by B& H Publishing Group in time for Christmas. The book will offer daily studies and reflections and a weekly dare for couples who "want to take the love dare to the next level," Stephen said.

With 23 years' marriage experience and 10 children between them, the Kendricks will then work on The Love Dare for Parents, with hopes of having it in stores before Christmas next year. The pair told Christian Retailing that they had recently received the green light for their next film project, through a process of prayer and discussion with other leaders at Sherwood Baptist Church in Albany, Ga., where Fireproof and their earlier films were made.

They declined to say what the new project was, other than "like the others, we want to impact families, to deal with issues that everyday people are going through," Alex said. "It's more about impact than entertainment."

Scriptwriting of the new project will start soon, with production due next year and a theatrical release planned for early 2011.
