The eleventh Doctor is Matt Smith.
He hasn't yet. The tenth doctor will be regenerating into the 11th Doctor around Christmas/New Year of 2009.
If you mean in doctor who it is the 11th doctor the actor is Matt smith
Matt Smith is the 11th Doctor. He will replace David Tennant.
there explaining that he's the 13th doctor because of doctor 8.5 in day of the doctor. they are probably saying that he's the 9th doctor, the 9th doctor is the 10th doctor, the 10th doctor is the 11th, the 11th is 12, so there fore he is the 13th doctor, hope that helped :)
The actor playing the 11th doctor is Matt Smith
Eventually yes, he will regenerate into the twelfth Doctor.
At the moment, The Doctor has regenerated 10 times, and Matt Smith is the 11th Doctor
Depends which doctor you are talking about- 10th Doctor= David Tennant 11th Doctor=Matt Smith.
