Though nobody has asked, I thought I would explain about Dr. Who. (See my blog of "Starting Anew, Again") While I was trying to find an appropriate picture in our very limited library, I came across this picture Sam took of his eye, and in a way, Dr. Who is the one who keeps "his eye" on us.
Dr. Who started out as a children's Sci-Fi show in Britain in the 60's that came over to the United States sometime in the '70's and has taken on a life of its own. Of the ten different actors that have portrayed the title role, Tom Baker is probably the most well known in the United States, playing the Doctor in the late 70's and early 80's.
The Doctor is an alien from a race of "Time Lord's", that make sure everything is kept safe from all the monsters and others who wish to take over the different worlds or affect the time of different worlds. Of course, throughout the thirty years or so, the majority of the Doctors spend their time on Earth. They each end up with "companions" that journey with them throughout their adventures. The Doctors have the ability to "regenerate" rather than die; this gives the series the ability to change the lead from time to time. Of course, as each Doctor takes his place, they all play the character a little differently, because the character is now different.
In 2004 Dr. Who came alive again, at least in the United States, and the latest Doctor, David Tennant has decided to hang up his doctor's coat, passing on the mantle to another Doctor to start filming in 2010, if it is picked up by the appropriate people who make such things happen. David Tennant has been the Doctor for the last three years, and is ready to move on. He (the actor) wanted to do Hamlet on stag, but they would not allow him out of his contract, so before he gets too identified with the Doctor, he is stepping aside. If history has anything to say about it, those who have played the Doctor the longest, like Tom Baker, get stuck as the Doctor, long after they have left the show; so David Tennant getting out while he can.
If you are interested in checking out the Doctor, the best place to start is with BBC Video. It is a great show with very loyal fans.
Peace and blessings.
