Ira Glass is a touchy talker. You wouldn't necessarily know this from
listening to his voice come through your radio or earbuds every week.
But several times throughout a 40-minute conversation, the host of "This
American Life" literally reaches out to engage, with a "whaddaya make of that?" light knee slap or an "I know! Isn't that crazy?" forearm squeeze.

tonight, Glass is all about showing the sorts of things that can't come
through speakers, as he hosts a live two-hour presentation of "This
American Life" that will beam into more than 500 cinemas nationwide.

a completely unnecessary extravaganza," he says, proudly, before
rattling off highlights that include animations, dancers, a short film

It makes sense that radio writers aren't exactly at the ready with things that can't be done on the radio, but how often does that happen when they come up empty-handed with an idea?

"That happens a lot, but we've got enough people, where if we say, 'Got anything about chickens?' somebody usually does," he says.
