Robert Knepper was on L.A's KROQ 106.7 giving an interview. I only caught the last few minutes but I'm waiting for KROQ to put the clip up on their site. The part I did catch was them talking about Fox putting Prison Break on hiatus for so long and Robert talking about the response from the fans. They talked a little bit about filming in Chicago. Bummed that I missed most of the interview.
They did mention that Wentworth was on the show a few weeks ago, which I never knew! Did anyone catch that interview? There's a link on the KROQ site for the interview here: http://www.kroq.com/kevinandbean/sounds.html
The interview is about halfway down.
