I just saw this over at tvshowsondvd. Looks like there's going to be quite a few extras, including something called Theme Scoring Sessions. Hmm...

I just put in the request for the review copy after receiving Paramount's PR release. Looks like a really nice set with plenty of extras!

I got a chuckle seeing that the "I dare you to knock this battery off my shoulder" commercial is being included as an extra. That may be all the incentive I need to get a show that I have to confess, I've never seen one episode of!

I just received my review copy and this is -- along with Image's Twilight Zone sets -- exactly how a TV Series ought to be treated on DVD.

Eight minutes of recording session audio (in dyanmic stereo!) with Markowitz conducting the main theme, plus a 10-minute audio interview with Markowitz, talking about why he didn't receive credit, the failed Dimitri Tiomkin-Paul Francis Webster theme that CBS ended up paying big-time NOT to use (too serious, apparently), and more...

Can't recommend this set highly enough if you're a fan of the show. The supplements are top-notch, and the full review will run in 2 weeks.
