The Couple who made "The Vow"

It's a staple of sappy movies, as well as of psychological dramas: the beautiful heroine (or handsome hero) with amnesia.
The May issue of the Costco warehouse store magazine includes a short write-up about Kim and Krickitt Carpenter, the real-life couple behind the movie "The Vow."

In case you missed the trailers (or the fairly decent reviews), the "inspired by a true story" movie portrays the challenges the Carpenters faced after a serious car accident left Krickett with no memory of ever having met her husband, much less of making vows in his regard.

As the couple note, it was a disappointment that the movie downplayed the pivotal role the Carpenters' Christian faith had in renewing their married life, but the book version doesn't hold back. The Carpenters are grateful that the movie, fictional as it is, is drawing readers to the fuller story--and (anecdotally), helping other couples "remember" their vows.

Have you seen the movie or read the book? What Theology of the Body threads do you find in the Carpenters' real-life living of their vow?
