Ira Glass just keeps moving to bigger and bigger media. First, his influential radio show started here in Chicago, then moved to cable TV as a Showtime series. Now he's hitting the big screen. "This American Life" — if you haven't yet seen the ads for it ahead of the movie trailers — is returning to movie screens for another one-night-only, live-via-satellite event to be broadcast to select movie theaters on April 23.

Glass will host a new episode of the program, joined by contributors Dan Savage, Starlee Kine, Mike Birbiglia, David Rakoff and Dave Hill. There will also be a new cartoon by Chris Ware, visuals by Arthur Jones and a very special appearance by Joss Whedon, creator of "Buffy the Vampire Slayer," "Firefly" and the current series "Dollhouse."
