Christianity Today has a good article on the wealth of pro-life movies that have been released in the past year by a usually pro-choice Hollywood.

Rob Johnston, professor of theology and culture at Fuller Theological Seminary, notes that with the exception of Bella, these films aren't being made by Christians.

"The church cannot take credit for this newfound interest [in pro-life storylines]," says Johnston, author of Reframing Theology and Film. "Rather, we need to thank a growing number of filmmakers for portraying the preciousness of life. All life has a sanctity that increasing numbers of people are recognizing."

Craig Detweiler, Johnston's colleague at Fuller and author of A Matrix of Meanings: Finding God in Pop Culture, says the "trend" may simply be a reflection of good storytelling principles—especially in comedies like Knocked Up.

"Comedies almost always end with weddings and births," says Detweiler. "That's the Shakespearean way. It's tough to turn an abortion into a comedic or happy ending, but a baby makes audiences coo and smile. Additionally, films are often about leaps of faith—and nothing takes more faith than bringing a child into this cracked and crazy world."

Here's hoping the trend continues.
