David Wheaton will have an hour-long conversation today with Professor Grant Horner on a biblical response to contemporary culture--including film, politics, mass media, art, pop culture, postmodernism. The show is on Sirius channel 161, and you can also listen online today (May 5) from 4-5 PM (EDT). I think you'll find his approach to film in particular to be interesting and helpful.
Here's an online print interview with Horner as well.
