It was NBC['s idea]. They were doing this big promotion inside of the Superbowl and handing out 150 million 3-D glasses, so we are the beneficiaries of that. Initially their plan was to have a bunch of shows do it, but it was logistically complicated, so "Chuck" seemed like the best fit for that type of thing... [You'll get to see] Jeff eating a urinal cake in 3-D. The director of [Medium's 2006 3-D] episode is actually our resident director, so he had lots of experience with 3-D, and the technology has come a long way.
[The show's use of guest-stars] began, for me, as a search for Steven Seagal and Jan Claude Van Damme. While that proved fruitless, there were a lot of other people interested in doing the show... I'm not giving up [on Seagal and Van Damme]!
