Brief overview of Doctor Who: Doctor Who is the world's longest running science fiction television series. It is about a Time Lord called The Doctor who travels through time and space in a blue police public call box called the TARDIS.
Some of these choices would be hard to lock in on a full TV series, I imagine this more in the vein of the Sherlock three hour and half hour episode series.
For the Doctor, I would start out with an older actor to do much the same thing William Hartnell did with the First Doctor.
The First Doctor
Reason: Donald Sutherland is a great actor and could really play the crotchety, old man that the Hartnell did. He would of course become more likeable over time. I imagine Sutherland in one maybe two stories before a regeneration.
The Doctor
Reason: Matthew Grey Gubler is great in
Criminal Minds as Dr. Spencer Reid. He really plays up the intelligence and I could easily see him being a mix of David Tennant and Matt Smith.
Companion
Reason: Melissa Rauch is great in
The Big Bang Theory and I could easily see her as a companion to a younger or older Doctor.
The Master
Reason: Liam Neeson in
Batman Begins looks eerily similar to Roger Delgado, the original Master. I think the dynamic of an older Master and Younger Doctor could play well if done properly. They are usually close in age and more than equals, the older/younger dynamic is intriguing. He would also be the reason for the Sutherland regeneration.
The Rani
Reason: It's kind of a no-brainer. I have seen her name thrown around in DW fancasts before and I have to agree. She's just a really good choice. Like in the original run, she would team up with The Master.
The Ice Warriors
Reason: I've always been a big fan of the Ice Warriors, and would love to see them make a return. I chose Ralph Fiennes for his Voldermort voice. The Ice Warriors are very hiss-y and low toned. He would be a great fit.
Ice Warriors/Cybermen Actor
Reason: Doug Jones may not get the notice Andy Serkis gets, but he is just as good. Doug Jones would be a perfect actor for Doctor Who.
Daleks
Daleks: No Daleks! The Daleks have become overused and need a rest. They would be mentioned and alluded to, but wouldn't come along for a few years. When they did come along, it would be the older style Daleks. I would also bring back the special weapons Dalek. This may be a controversial decision, but it's my fancast so take that.
Cybermen/Dalek Voice
Reason: Nicholas Briggs IS the voice of the Cybermen and Daleks, it would be impossible to get the same feeling from any other person.
