CSI: 5.1

The special feature, entitled The Research Of CSI: Maintaining The Accuracy, is entirely predictable - talking heads, professional outsiders, yes they take it seriously. No one admits to making anything up, certainly not with the science, although Carol Mendelsohn, one of the producer/writers, says that "the biggest liberty we take is with time" - in other words, if something in real life takes 10 days, in a CSI episode it takes 10 minutes.

The five commentaries with assorted writers, directors, producers and actor George Eads (once) are surprisingly bland and introspective. Repartee ("Good lookin' cast" , "Yeah") seldom wipes the sleep out of your eyes. "Proms are different in Las Vegas." Wow!

When exec producer/writer/director Danny Cannon says, "Billy wants to be the nerd," you need an interpreter. "Billy" is William Petersen, aka Gil Grissom, and "nerd" refers to his work in the science lab. What is meant here is that the star of the show doesn't like to be a headliner; but prefers to be a backroom boy.

Did you know that there are 35 miles of tunnel under Las Vegas - that's sewage tunnels? Did you know that a lot of the series is shot in Los Angeles? Did you know that Sir Arthur Conan Doyle, creator of Sherlock Holmes, the world's most famous fictional detective, had two sons, Dennis and Kingsley, and when Rich Catalani and David Rambo wrote the episode Who Killed Sherlock, they named the victim and Holmes fanatic, Dennis Kingsley, and - guess what - two guys from Denmark picked up on it.

Well, hotdiggedy!
