The FilmInFocus series “Behind the Blog” continues this week with a new entry: Matt Zoller Seitz and his “The House Next Door.”

An excerpt:

HOW HAS YOUR LIFE CHANGED BECAUSE OF YOUR BLOG? HAS IT GONE IN ANY NEW DIRECTIONS BECAUSE OF YOUR NEWFOUND PROMINENCE?

Throughout my career, I always took my work seriously, but I also had a skeptical or even cynical attitude about it — that it was just something people read at breakfast or on the bus to kill time. But since I started the blog I’ve been contacted by a lot of people who have been reading me closely for years and can quote lines or passages from pieces that I’d forgotten I even wrote. That kind of feedback means more to me than any professional honor I’ve ever received. It’s the Christmas party scene at the end of It’s a Wonderful Life where George Bailey learns that his existence meant something.
