To play the 8th doctor. Harrison Ford turned it down because he didn't wanna work in television,Tom hanks really wanted to do it and was a huge fan of the show,but didn't wanna upset fans by the Doctor being played by an American and Jim Carey turned it down because he never heard of the show and didn't wanna upset fans either.
How do you think they would have played the Doctor? Jim is one I would have a hard time thinking about. I don't remember when he got into dramas so I don't know if he would have played the Doctor as a goofball or he would have played him seriously.
Harrison Ford I could have almost seen him playing it like a Han Solo Doctor which would have been awesome if he did play the Doctor.
Tom Hanks would probably have a hint of the character he played in the Da Vinci code.
